Afferent Projections of the Clare-Bishop Area in the Cat Cortex: A Horseradish Peroxidase Study
ثبت نشده
چکیده
Recent studies of the Clare-Bishop (CB) area (the lateral suprasylvian area) have supported the role of this extrastriate, retinotopically-organized cortical region in visual and oculomotor functions. Anatomical studies were undertaken using retrograde horseradish peroxidase (HRP) techniques to define its afferent connections. Results indicate that CB receives substantial input from the ipsilateral striate and parastriate visual cortex (areas 17, 18 and 19), the contralateral CB area, claustrum, thalamus (ventral anterior nucleus, intralaminar nuclei, LP-pulvinar complex, posterior nucleus, dorsal lateral geniculate nucleus), and several brain stem nuclei (rostral linear nucleus, ventral tegmental area of Tsai, locus ceruleus, raphe nuclei). The results of the present investigation provide an anatomical substrate for the proposed role of the Clare-Bishop area in visual and oculomotor functions. OHIOJ. SCI. 82(1): 38, 1982

Lack of projections from medial geniculate body to suprasylvian cortex in cat: a study with horseradish peroxidase.
Because both electrophysiological and behavioral methods have implicated the suprasylvian cortex of cat in audition, its afferents were studied using retrograde transport of horseradish peroxidase. The bulk-filling method was used to maximize the likelihood that virtually all afferents to the area would be labeled. Despite the vivid retrograde labeling of many thalamic cells with this procedure...
متن کاملFunctional organization of input from areas 17 and 18 to an extrastriate area in the cat.
In the cat, areas 17 and 18 have 2 main cortical targets: area 19 and a large region of suprasylvian cortex, referred to here as the Clare-Bishop area (Hubel and Wiesel, 1969). The functional organization of the latter area is not well understood. It seems likely that its organization reflects, in part, the organization of its inputs from areas 17 and 18, and I therefore studied the functional ...
متن کاملSENSORIMOTOR CONTROL OVER FUSIMOTOR NEURONS OF THE TENUISSIMUS MUSCLE IN THE A NESTHETIZED CAT: A QUALITATIVE PRIMARY AFFERENT RECORDING
Cortical control of the sensory output of muscle spindles was studied in thirteen anesthetized cats in the present experiment. Gamma motoneuron activity was monitored during electrical stimulation of the sensorimotor cortex while recording from single primary afferents from the tenuissimus muscle. Findings are as follows: 1. The state of anesthesia is crucial in obtaining reproducible resu...
متن کاملCallosal projections in rat somatosensory cortex are altered by early removal of afferent input.
During the first postnatal week, the distribution of callosal projection neurons in the rat somatosensory cortex changes from a uniform to a discontinuous pattern. To determine if this change is influenced by afferent inputs to the somatosensory cortex, the effect of both early unilateral infraorbital nerve section and unilateral removal of the dorsal thalamus on the distribution of callosal pr...
متن کاملSpinal projections of cat primary afferent fibers innervating caudal facet joints.
The spinal projections of afferent fibers innervating the facet joints between caudal vertebrae were examined by the use of anterograde transport of wheat germ agglutinin-horseradish peroxidase (WGA-HRP). Experiments were performed on 5 adult cats in which spinal dorsal roots below the 2nd sacral segment (S2) on the right side were cut. Injections of WGA-HRP into the caudal facet joints gave ri...
