    Neural lateralization of species-specific vocalizations by Japanese macaques (Macaca fuscata) (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-10-20
    Description: Five Japanese macaques and five other Old World monkeys were trained to discriminate among field-recorded Japanese macaque vocalizations. One task required discrimination of a communicatively relevant acoustic feature ("peak"), and a second required discrimination of an orthogonal feature of the same vocalizations ("pitch"). The Japanese animals more proficiently discriminated the peak feature when stimuli were presented to the right ear (primarily left cerebral hemisphere), as opposed to the left ear (primarily right hemisphere). In discriminating the pitch feature, the Japanese animals either showed (i) a left-ear processing advantage or (ii) no ear advantage. The comparison animals, with one exception, showed no ear advantage in processing either feature of the vocalizations. The results suggest that Japanese macaques engage left-hemisphere processors for the analysis of communicatively significant sounds that are analogous to the lateralized mechanisms used by humans listening to speech.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Petersen, M R -- Beecher, M D -- Zoloth, S R -- Moody, D B -- Stebbins, W C -- New York, N.Y. -- Science. 1978 Oct 20;202(4365):324-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/99817" target="_blank"〉PubMed〈/a〉

    Species-specific perceptual processing of vocal sounds by monkeys (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-05-25
    Description: Monkeys of four species were trained to discriminate between sets of natural tonal calls of Japanese macaques (Macaca fuscata) by the position of a frequency-inflection peak or by initial pitch. The Japanese macaques consistently performed best on peak position and the other species on pitch. The results imply special strategies for perceptional processing of vocal sounds and suggest parallels with human speech perception.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zoloth, S R -- Petersen, M R -- Beecher, M D -- Green, S -- Marler, P -- Moody, D B -- Stebbins, W -- New York, N.Y. -- Science. 1979 May 25;204(4395):870-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/108805" target="_blank"〉PubMed〈/a〉

    Description: A nonpeptide morphine-like compound (MLC) which cross reacts with morphine-specific antibodies has been localized with the use of immunocytochemistry.

    Another flame retardant, tris-(1,3-dichloro-2-propyl)-phosphate, and its expected metabolites are mutagens (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-05-19
    Description: A flame retardant used in children's sleepwear, tris-(1,3-dichloro-2-propyl)phosphate (Fyrol FR2) is a mutagen in the Salmonella-mammalian tissue homogenate test after it has been activated by mouse or rat liver homogenate. The expected enzymatic hydrolysis product, 1,3-dichloro-2-propanol, is similarly a mutagen after activation by liver homogenate. A proposed metabolite of the flame retardant, 1,3-dichloro-2-propanone, is a potent mutagen in the absence of such activation. A flame retardant with similar structure, tris-(2,3-dibromopropyl)phosphate (tris-BP), was shown previously to be a mutagen, to cause sterility in animals, to be a carcinogen, and to be absorbed through human skin. These and other flame retardants have characteristic nuclear magnetic resonance spectra that can be used to determine which flame retardant is present in commercially purchased sleepwear. Sleepwear treated with tris-BP, Fyrol FR2, and other chemical additives was being sold in late 1977.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gold, M D -- Blum, A -- Ames, B N -- New York, N.Y. -- Science. 1978 May 19;200(4343):785-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/347576" target="_blank"〉PubMed〈/a〉

    Localization of primate calls by old world monkeys (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-08-25
    Description: Monkeys (Macaca) were trained by operant conditioning techniques to report the minimum detectable change in location of a sound in space, and were tested with a series of recorded coo or clear call vocalizations. Acuity of localization varied from approximately 4 degrees to 15 degrees and was a function of the magnitude of the change in pitch (frequency modulation) of the different clear calls.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Brown, C H -- Beecher, M D -- Moody, D B -- Stebbins, W C -- New York, N.Y. -- Science. 1978 Aug 25;201(4357):753-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/97785" target="_blank"〉PubMed〈/a〉

    beta1- and beta2-Adrenergic receptors in rat cerebral cortex are independently regulated (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-05-25
    Description: Repeated administration of the tricyclic antidepressant desmethylimipramine to adult rats for 10 days caused a 40% decrease in the density of beta1-adrenergic receptors in the cerebral cortex but had no effect on the density of beta2-adrenergic receptors. Conversely, destruction of noradrenergic neurons by administration of 6-hydroxydopamine to neonatal rats caused a 64% increase in the density of beta1-adrenergic receptors in adult cerebral cortex with no change in the density of beta2-adrenergic receptors. These results suggest that the beta-adrenergic receptors in rat cortex involved in neuronal function are primarily of the beta1 subtype.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Minneman, K P -- Dibner, M D -- Wolfe, B B -- Molinoff, P B -- New York, N.Y. -- Science. 1979 May 25;204(4395):866-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/35829" target="_blank"〉PubMed〈/a〉

    Mullerian duct regression in the embryo correlated with cytotoxic activity against human ovarian cancer (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-08-31
    Description: A significant cytotoxicity index was obtained when human ovarian cancer cells in a microcytotoxicity assay were exposed during the S (DNA-synthesizing) phase of the cell cycle to purified fractions of testis exhibiting high Mullerian inhibiting substance bioactivity. The same effect was not observed when these fractions were tested against human glioblastoma or fibroblast lines. Most human ovarian cancers are said to resemble Mullerian tissues histologically. Mullerian inhibiting substance may thus deserve further study as a potential chemotherapeutic agent.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Donahoe, P K -- Swann, D A -- Hayashi, A -- Sullivan, M D -- New York, N.Y. -- Science. 1979 Aug 31;205(4409):913-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/472712" target="_blank"〉PubMed〈/a〉

    Description: Brains of juvenile gray bats, Myotis grisescens, found dead beneath maternity roosts in two Missouri caves contained lethal concentrations of dieldrin. One colony appeared to be abnormally small, and more dead bats were found a year after the juvenile bats had been collected.

    Symbolic communication between two chimpanzees (Pan troglodytes) (1978)

    Publication Date: 1978-08-18
    Description: Through use of learned symbols, two chimpanzees accurately specified 11 foods by name to one another when the food item's identity was known by only one. They could not do this when denied use of the symbols. The chimpanzees then spontaneously requested specific foods of one another by name. Requests resulted in cooperative and reciprocal symbolically mediated food exchange.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Savage-Rumbaugh, E S -- Rumbaugh, D M -- Boysen, S -- New York, N.Y. -- Science. 1978 Aug 18;201(4356):641-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/675251" target="_blank"〉PubMed〈/a〉
