    A major direct GABAergic pathway from zona incerta to neocortex (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-06-22
    Description: Retrograde fluorescent tracers were used to demonstrate a previously unknown but sizable direct gamma-aminobutyric acid (GABA)-containing neuronal pathway from the zona incerta to the neocortex in rats. This incertocortical pathway was found to project bilaterally to the entire neocortex and exhibited a rough corticotopic organization. Many of the zona incerta neurons projecting to the parietal and occipital cortices could also be immunohistochemically stained with antibodies to glutamic acid decarboxylase and GABA. Few of these neurons were immunoreactive to tyrosine hydroxylase antibodies, which identify dopamine-containing neurons. Injections in the frontal and entorhinal cortices labeled many neurons near or within the dopaminergic A13 subdivision of the zona incerta. In addition, the incertocortical system was found to be significantly larger during early postnatal (2 to 3 weeks) development. The projection pattern of this newly discovered pathway resembles that of the monoaminergic and cholinergic systems, arising from the brainstem and forebrain, suggesting possible similarities of function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lin, C S -- Nicolelis, M A -- Schneider, J S -- Chapin, J K -- AA 06965/AA/NIAAA NIH HHS/ -- KO2-AA 00089/AA/NIAAA NIH HHS/ -- NS 26722/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1990 Jun 22;248(4962):1553-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physiology and Biophysics, Hahnemann University, Philadelphia, PA 19102.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2360049" target="_blank"〉PubMed〈/a〉

    Sensorimotor encoding by synchronous neural ensemble activity at multiple levels of the somatosensory system (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-06-02
    Description: Neural ensemble processing of sensorimotor information during behavior was investigated by simultaneously recording up to 48 single neurons at multiple relays of the rat trigeminal somatosensory system. Cortical, thalamic, and brainstem neurons exhibited widespread 7- to 12-hertz synchronous oscillations, which began during attentive immobility and reliably predicted the imminent onset of rhythmic whisker twitching. Each oscillatory cycle began as a traveling wave of neural activity in the cortex that then spread to the thalamus. Just before the onset of rhythmic whisker twitching, the oscillations spread to the spinal trigeminal brainstem complex. Thereafter, the oscillations at all levels were synchronous with whisker protraction. Neural structures manifesting these rhythms also exhibited distributed spatiotemporal patterns of neuronal ensemble activity in response to tactile stimulation. Thus, multilevel synchronous activity in this system may encode not only sensory information but also the onset and temporal domain of tactile exploratory movements.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nicolelis, M A -- Baccala, L A -- Lin, R C -- Chapin, J K -- DE11121-01/DE/NIDCR NIH HHS/ -- NS-26722/NS/NINDS NIH HHS/ -- NS-29161/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1995 Jun 2;268(5215):1353-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anatomy and Neurobiology, Medical College of Pennsylvania, Philadelphia, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7761855" target="_blank"〉PubMed〈/a〉
