The somatosensory cortex of the rodent [PDF]
Trends in Neurosciences, 1983 Abstract The anatomical and functional organization of rodent somatosensory cortex is reviewed in light of recent evidence which suggests that there are areal differences in functional organization and afferent and efferent connections within somatosensory cortex.

Postictal inhibition of the somatosensory cortex
Neurological Sciences, 2010Transient suppression of the motor cortex and of the speech areas cause well-described postictal phenomena following seizures involving the respective cortical areas. Pain is a rare symptom in epileptic seizures. We present a patient with painful tonic seizures in the left leg.

Map Plasticity in Somatosensory Cortex
Science, 2005Sensory maps in neocortex are adaptively altered to reflect recent experience and learning. In somatosensory cortex, distinct patterns of sensory use or disuse elicit multiple, functionally distinct forms of map plasticity. Diverse approaches—genetics, synaptic and in vivo physiology, optical imaging, and ultrastructural analysis—suggest a distributed ...

Synaptogenesis in Monkey Somatosensory Cortex
Cerebral Cortex, 1991The time course and rate of synaptogenesis were studied in the somatosensory cortex (Brodmann's areas 1 and 3b) of 27 rhesus monkeys ranging in age from embryonic day 41 to 20 years. Two to four vertical probes, each consisting of a series of overlapping electron micrographs and extending from the pial surface to the interface of the cortex with the ...

The somatosensory cortex [PDF]
, 1996 Mammals vary in the number of cortical areas involved in processing somatosensory information. Most mammals appear to have areas S1, S2, and PV, as well as strip-like somatosensory areas along the rostral and caudal borders of S1. In monkeys and other higher primates, cortex caudal to S1 is differentiated into areas 1 and 2, each also representing ...

Somatotopic astrocytic activity in the somatosensory cortex
Glia, 2013AbstractAstrocytes play a crucial role in maintaining neuronal function and monitoring their activity. According to neuronal activity maps, the body is represented topographically in the somatosensory cortex. In rats, neighboring cortical areas receive forelimb (FL) and hindlimb (HL) sensory inputs. Whether astrocytic activity is also restricted to the

Journal of Comparative Neurology, 1991
AbstractMultiunit microelectrode recording techniques were used to delineate the somatotopic organization of the secondary somatosensory cortex (SII) of the neonatal pig. Barbiturate anesthetized piglets ranging in age from 7 days preterm to 2 months postpartum were used.

Interhemispheric connections of the somatosensory cortex in the rabbit [PDF]
Journal of Comparative Neurology, 1987 AbstractCorpus callosal connections of somatosensory cortex were studied in rabbits by combining anatomical tracing and electrophysiological mapping in the same animals. The results show that callosal connections are unevenly distributed in SI and SII. In SI, the representations of all body surfaces caudal to the neck and midline structures of the head

The somatosensory cortex in multiple system atrophy
Journal of the Neurological Sciences, 2008In multiple system atrophy (MSA), it has been accepted that the motor-related cortical area may degenerate. However, there have been few investigations of the postcentral cortex of the somatosensory area. For this reason, we investigated the effects of MSA on both the precentral and the postcentral cortex and were able to demonstrate degenerative ...

Control of Somatosensory Input by Cerebral Cortex [PDF]
Science, 1966 Direct stimulation of the pyramidal tract increases the size of the excitatory receptive fields of neurons in the somatosensory cortex of the cat. This effect reflects greater transmission of cutaneous information through the dorsal column nuclei as a result of the facilitation of cells in these nuclei by pyramidal tract fibers.
