    Ethanol specifically potentiates GABA-mediated neurotransmission in feline cerebral cortex (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-08-08
    Description: Ethanol (ethyl alcohol) potentiates the inhibition of cortical neurons by gamma-aminobutyric acid. This effect is specific, since ethanol does not potentiate inhibiton by glycine, serotonin, or dopamine. These results have implications for alcoholism because (i) gamma-aminobutyric acid mediates anxiolytic mechanisms, and (ii) anxiety is implicated in the etiology of alcoholism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nestoros, J N -- New York, N.Y. -- Science. 1980 Aug 8;209(4457):708-10.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7394531" target="_blank"〉PubMed〈/a〉

    Binocularity in the cat visual cortex is reduced by sectioning the corpus callosum (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-03-07
    Description: In the normal cat, most cells in area 17 can be binocularly driven. Sectioning the corpus callosum results in a significant reduction in binocularly driven cells. Normal binocular vision is thus dependent on the corpus callosum.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Payne, B R -- Elberger, A J -- Berman, N -- Murphy, E H -- New York, N.Y. -- Science. 1980 Mar 7;207(4435):1097-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7355278" target="_blank"〉PubMed〈/a〉

    Unequal alternating monocular deprivation causes asymmetric visual fields in cats (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-04-25
    Description: Kittens were reared so that each eye received normal patterned vision on alternate days. If the eyes received equal periods of stimulation, the visual fields were normal. If one eye received much more experience than the other, the field of the less experienced eye was restricted to the temporal hemifield. This change, which differs from that observed when one or both eyes are deprived continuously of patterned input, suggests that an imbalance in the duration of stimulation can influence the outcome of the normal competitive interaction between pathways from the two eyes and can cause a selective suppression of a portion of the input from the less experienced eye. This suppression may involve the ipsilateral retino-geniculo-cortical pathways or it may involve the entire cortical pathway from the less experienced eye, leaving the colliculus to control responses to visual targets.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tumosa, N -- Tieman, S B -- Hirsch, H V -- New York, N.Y. -- Science. 1980 Apr 25;208(4442):421-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7367872" target="_blank"〉PubMed〈/a〉

    A new laser scanning system for measuring action potential propagation in the heart (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-10-23
    Description: A rapid laser scanning system was developed to map the spread of excitation in amphibian and mammalian hearts stained with fluorescent dye. Isochronic maps of conduction were constructed by timing the upstroke of the optical action potential; 128 sites could be scanned in 4 milliseconds. The accuracy of this technique was verified by recording simultaneously from 16 unipolar electrodes placed in different areas of the heart. Conducted action potentials in normal frog heart propagated at 0.1 meter per second. Propagation of action potentials was also monitored in ischemic cat heart, in which both driven and arrhythmic action potential upstrokes could be tracked. The results suggest that this system is capable of scanning the normal and abnormal spread of electrical activity in the heart.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dillon, S -- Morad, M -- New York, N.Y. -- Science. 1981 Oct 23;214(4519):453-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6974891" target="_blank"〉PubMed〈/a〉

    Merkel cell receptors: structure and transducer function (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-10-09
    Description: An electron microscopic and electrophysiological investigation was made of Merkel cell-neurite complexes in the sinus hair follicles of the cat. These mechanoreceptors respond with very precise phase locking to heavy-frequency vibratory stimuli as well as to static hair displacements. The mechanoelectric transduction process is faster than that known for any other somatic mechanoreceptor. These data show that the nerve endings themselves and not the Merkel cells are the mechanoelectric transducer elements in these receptors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gottschaldt, K M -- Vahle-Hinz, C -- New York, N.Y. -- Science. 1981 Oct 9;214(4517):183-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7280690" target="_blank"〉PubMed〈/a〉

    Retinal ganglion cell classes in the Old World monkey: morphology and central projections (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-09-04
    Description: Labeled ganglion cells were studied in whole-mount retinas of Old World monkeys after electrophoretic injections of horseradish peroxidase into physiologically characterized sites. A number of different morphological classes have been identified, each of which has a distinctive pattern of central projection. Since different functional classes of primate retinal ganglion cells also have distinctive patterns of central projection, correspondences between functional and morphological cell types have been inferred. There prove to be parallels between morphological types of cat monkey ganglion cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Leventhal, A G -- Rodieck, R W -- Dreher, B -- EY-02923/EY/NEI NIH HHS/ -- EY-03427/EY/NEI NIH HHS/ -- EY-05212/EY/NEI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1981 Sep 4;213(4512):1139-42.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7268423" target="_blank"〉PubMed〈/a〉

    Publication Date: 1981-09-04
    Description: Recovery of visual acuity was studied in six long-term monocularly deprived cats after removal of the nondeprived eye or reverse lid suture. Although both manipulations improved visual acuity, removal of the nondeprived eye was associated with more rapid recovery and higher find acuity than in reverse suture. These results are in agreement with the known electrophysiological effects of these recovery conditions and are also similar to the effects of reverse occlusion or loss of the nonamblyopic eye in human amblyopes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smith, D C -- EYO 7005/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 1981 Sep 4;213(4512):1137-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7268422" target="_blank"〉PubMed〈/a〉

    Intrinsic birefringence signal preceding the onset of contraction in heart muscle (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-08-07
    Description: An intrinsic birefringence signal with two components occurring before sarcomere shortening was measured in mammalian cardiac muscle. The second component was sensitive to the inotropic state of the muscle as affected by external calcium concentration and epinephrine but not by changes of resting length. The second component was absent in frog heart. These results suggest that the second component of the birefringence signal reflects the activity of the sarcoplasmic reticulum related to excitation-contraction coupling processes occurring prior to onset of contraction in mammalian cardiac muscle.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Weiss, R -- Morad, M -- New York, N.Y. -- Science. 1981 Aug 7;213(4508):663-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7256266" target="_blank"〉PubMed〈/a〉

    Hindbrain GABA receptors influence parasympathetic outflow to the stomach (1981)

    Publication Date: 1981-10-09
    Description: Blockade of gamma-aminobutyric acid receptor function by direct microinjection of bicuculline into the nucleus ambiguous in cats produced a marked increase in gastric motility which was mediated by the vagus nerve. This effect was reversed by muscimol. These data indicate that the nucleus ambiguous may be an important brain site influencing gastric function and that the neurotransmitter controlling parasympathetic overflow from this nucleus to the stomach is gamma-aminobutyric acid.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Williford, D J -- Ormsbee, H S 3rd -- Norman, W -- Harmon, J W -- Garvey, T Q 3rd -- DiMicco, J A -- Gillis, R A -- New York, N.Y. -- Science. 1981 Oct 9;214(4517):193-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6269182" target="_blank"〉PubMed〈/a〉

    Publication Date: 1980-01-04
    Description: Neurons in the visual cortex of monkeys and cats have been characterized as either (i) bar and edge detectors or (ii) cells selective for certain spatial frequencies. To assess which of these functional descriptions is more accurate, we measured (i) the selectivity and (ii) the responsivity-sensitivity of these neurons to bars of various widths and gratings of various spatial frequencies. All of the cells recorded from were considerably more selective along the dimension of spatial frequency than along the dimension of bar width. Further, most were more responsive and sensitive to the grating of optimal frequency than to the bar of optimal width.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Albrecht, D G -- De Valois, R L -- Thorell, L G -- New York, N.Y. -- Science. 1980 Jan 4;207(4426):88-90.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6765993" target="_blank"〉PubMed〈/a〉

    Release of immunoreactive serotonin into the lumen of the feline gut in response to vagal nerve stimulation (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-09-11
    Description: Immunoreactive serotonin was detected in the lumen of the proximal jejunum of food-deprived cats. During perfusion of this intestinal segment in vivo, there was a constant basal rate of intraluminal secretion of this amine. The rate of secretion was significantly increased during efferent electrical stimulation of the cut cervical vagal nerves. This stimulatory effect was not altered after bilateral adrenalectomy was performed in the same animals. A synchronous release of substance P into the gut lumen was also demonstrated during vagal stimulation. During the period of increased intraluminal secretion of immunoreactive serotonin, there was no demonstrable change in the portal or systemic blood levels of this amine.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ahlman, H -- DeMagistris, L -- Zinner, M -- Jaffe, B M -- 5R01AM2652202/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1981 Sep 11;213(4513):1254-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6168020" target="_blank"〉PubMed〈/a〉

    Description: The opiate antagonist naloxone has been used to treat cats subjected to cervical spinal trauma. In contrast to saline-treated controls, naloxone treatment significantly improved the hypotension observed after cervical spinal injury. More critically, naloxone therapy significantly improved neurologic recovery. These findings implicate endorphins in the pathophysiology of spinal cord injury and indicate that narcotic antagonists may have a therapeutic role in this condition.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Faden, A I -- Jacobs, T P -- Holaday, J W -- New York, N.Y. -- Science. 1981 Jan 30;211(4481):493-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7455690" target="_blank"〉PubMed〈/a〉

    Discharge patterns of hindlimb motoneurons during normal cat locomotion (1981)

    Details
    Publication Date: 1981-07-24
    Description: Long-term recording from single lumbar motoneurons of intact cats revealed activation patterns fundamentally different from those seen in decerebrate preparations. In intact cats, motoneuron bursts showed marked rate modulation without initial doublets. Each unit's frequencygram generally resembled the envelope of the gross electromyogram simultaneously recorded from the corresponding muscle. Average and peak discharge rates increased for faster gaits. These findings suggest that, in cat locomotion, rate modulation is a more important contributor to force regulation than was previously thought.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hoffer, J A -- O'Donovan, M J -- Pratt, C A -- Loeb, G E -- New York, N.Y. -- Science. 1981 Jul 24;213(4506):466-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7244644" target="_blank"〉PubMed〈/a〉

    Electroretinographic responses to alternating gratings before and after section of the optic nerve (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-02-27
    Description: Electroretinographic (ERG) responses to sinusoidal gratings reversed in contrast (pattern-reversal ERG) were recorded from both eyes of cats before and after unilateral section of the optic nerve. In the eye ipsilateral to the section, the pattern-reversal ERG remained unaltered for a few days after the section, the progressively decreased in amplitude, first at low and then at high spatial frequencies, to disappear completely about 4 months after the section, when ganglion cell degeneration was practically complete. The flash ERG remained unaltered. No alteration was observed in the contralateral eye.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mafei, L -- Fiorentini, A -- New York, N.Y. -- Science. 1981 Feb 27;211(4485):953-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7466369" target="_blank"〉PubMed〈/a〉

    Pituitary gastrins occur in corticotrophs and melanotrophs (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-08-14
    Description: The gut hormone gastrin was identified in pituitary cells containing adrenocorticotropic hormone and alpha-melanocyte--stimulating hormone by region-specific immunocytochemistry and radioimmunoassay. Smaller amounts of gastrin were found in nerve fibers of the neural lobe and pituitary stalk. Since adrenocorticotropic hormone--like peptides occur in antropyloric gastrin cells, these data indicate a considerable similarity in peptide composition of pituitary and gastrointestinal endocrine cells and reinforces questions of multiple hormone production.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Larsson, L I -- Rehfeld, J F -- New York, N.Y. -- Science. 1981 Aug 14;213(4509):768-70.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6266012" target="_blank"〉PubMed〈/a〉

    Exercise hyperpnea and locomotion: parallel activation from the hypothalamus (1981)

    Details
    Publication Date: 1981-02-20
    Description: Unanesthetized decorticate cats walked or ran normally on a treadmill either spontaneously or during electrical stimulation of the subthalamic "locomotor" region. The respiratory response usually preceded the locomotor response and increased in proportion to locomotor activity despite control or ablation of respiratory feedback mechanisms. Respiration increased similarly in paralyzed animals during fictive locomotion despite the absence of muscular contraction or movement. Hypothalamic command signals are thus primarily responsible for the proportional driving of locomotion and respiration during exercise.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Eldridge, F L -- Millhorn, D E -- Waldrop, T G -- HL-17106/HL/NHLBI NIH HHS/ -- HL-17689/HL/NHLBI NIH HHS/ -- NS-11132/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1981 Feb 20;211(4484):844-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7466362" target="_blank"〉PubMed〈/a〉

    Growth and reshaping of axons in the establishment of visual callosal connections (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-05-15
    Description: The visual cortical areas in the two hemispheres are interconnected by axons running through the corpus callosum. In adult cats, these axons originate from, and terminate in, tangentially restricted portions of each area. In young kittens, however, callosal axons originate from the entire extent of each area, although they apparently enter the gray matter only in the restricted regions where they will also be found in adults. In kittens, but not in adults, callosal axons also reach other regions, but there they appear to be confined to the lowest part of layer VI. During the first two postnatal months, the callosal efferent zones become progressively restricted to their adult locations. During this process, many neurons eliminate the axons (or axon collaterals) that they had formerly sent through the corpus callosum and form permanent connection ipsilaterally.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Innocenti, G M -- New York, N.Y. -- Science. 1981 May 15;212(4496):824-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7221566" target="_blank"〉PubMed〈/a〉

    Description: Application of arachidonic acid or prostaglandin G(2) to the brain surface of anesthetized cats induced cerebral arteriolar damage. Scavengers of free oxygen radicals inhibited this damage. Prostaglandin H(2), prostaglandin E(2), and 11,14,17-eicosatrienoic acid did not produce arteriolar damage.

    Description: Twenty adjacent ganglion cells in cat retina were partially reconstructed from electron micrographs of serial thin sections. Cells were classified by size and by dendritic branching patterns as alpha, beta, or gamma cells. The alpha and beta cells were further subdivided by differences in the laminar distribution of their dendrites in the inner plexiform layer. The distribution of synaptic contacts on the cells was distinctive for each of the five major classes. Contacts on the alpha and beta cells were mainly on the dendrites in the sublamina in which a cell's major dendritic arborization was contained.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stevens, J K -- McGuire, B A -- Sterling, P -- New York, N.Y. -- Science. 1980 Jan 18;207(4428):317-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7350663" target="_blank"〉PubMed〈/a〉

Their brains contained an excess of GM2 and GM3 gangliosides, and their livers a nine- to tenfold excess of sphingomyelin and cholesterol. A total deficiency of lysosomal (pH 5.0) sphingomyelinase was found in the leukocytes, liver, and brain of the cats, although the activity of the microsomal (pH 7.4, magnesium-dependent) sphingomyelinase was normal in brain.

    Electromyograms are repeatable: precautions and limitations (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-11-14
    Description: Electromyograms recorded by bipolar, fine wire electrodes placed into anatomically equivalent sites in skeletal muscles of vertebrates are repeatable when the animals use the muscles in a similar way. Repeatability applies to the number of spikes recorded from a given site and to their average amplitude as well as to the root-mean-square value, though the values obtained for these descriptors differ among muscles, and perhaps fascicles, of particular animals even when the animals are performing equivalent actions. Tests suggest that these results are not affected by the nature of most kinds of recording equipment. Also, substantial differences in electrode tip configuration and wire diameter induce relatively minor, less than 8 percent, differences in electrode resistance and impedance. Doubling the length of the fine wire leads produces less than an 8 percent (15 percent when the length is tripled) effect; however, the effect of electrode material may be as much as 85 percent in resistance and 20 percent in impedance. Reports of nonreproducibility or variability of electromyograms apparently result mainly from anatomically inexact placement into physiologically and histochemically different fascicles of compound muscles, from recordings of muscles that are active at very low levels, and perhaps from comparison among recordings of muscles that really differ in their activity level.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gans, C -- Gorniak, G C -- DHEW-PHS-G 1R01DE052112-01/DE/NIDCR NIH HHS/ -- New York, N.Y. -- Science. 1980 Nov 14;210(4471):795-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7433997" target="_blank"〉PubMed〈/a〉

    Description: Nerve processes and cell bodies containing leucine enkephalin were demonstrated in the sacral autonomic nucleus of the cat by immunocytochemical methods. Enkephalinergic preganglionic perikarya were seen only when axonal transport was blocked either by colchicine or by ventral root ligation. Ligation of the sacral ventral roots also produced damming of enkephalin immunoreactivity proximal to the S2 ligature. These data indicate that parasympathetic preganglionic neurons synthesize and transport enkephalin or enkephalin-like immunoreactive compounds to the periphery.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Glazer, E J -- Basbaum, A I -- New York, N.Y. -- Science. 1980 Jun 27;208(4451):1479-81.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6155697" target="_blank"〉PubMed〈/a〉
