Habituation in the somatosensory cortex
Neurophysiology, 1980Responses of neurons without spontaneous activity ("silent") to prolonged stimulation of the mesenteric nerves were studied in cats anesthetized with chloralose (65–70 mg/kg) and immobilized with flaxedil. The results showed that neurons of the association and primary projection areas are characterized by habituation to prolonged stimulation of ...

Homeostatic Metaplasticity in the Human Somatosensory Cortex
Journal of Cognitive Neuroscience, 2008Abstract Long-term potentiation (LTP) and long-term depression (LTD) are regulated by homeostatic control mechanisms to maintain synaptic strength in a physiological range. Although homeostatic metaplasticity has been demonstrated in the human motor cortex, little is known to which extent it operates in other cortical areas and how it ...

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 ...

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.

Journal of Comparative Neurology, 1991
AbstractThe cerebral cortex of adult mammals contains several somatotopic representations of the body surface. Although the organization of the various somatosensory cortices of numerous species of adult animals has been elucidated, data on the somatosensory representations of fetal and neonatal animals are limited. As part of an investigation into the

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 ...

The somatosensory cortex of the rodent
Trends in Neurosciences, 1983Abstract 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.

Rat Navigation by Stimulating Somatosensory Cortex
Journal of Bionic Engineering, 2019One of the most important topics in neuroscience is the issue of brain electrical stimulation and its widespread use. Based on this issue, rat robot, a rat navigation system was introduced in 2002, which has utilized brain electric stimulations as a guide and a reward for driving rats.

Organization of primary somatosensory cortex in the cat
Journal of Neurophysiology, 19801. Multi-unit recordings were made from SI cortex of barbiturte-anesthetized cats. In four cats, multiple vertical penetrations were made at closely spaced intervals. In 12 cats, long surface-parallel penetrations were made in the rostrocaudal or the lateromedial directions with observations taken every 100 micron. 2.

Somatosensory cortex: a ‘new’ somatotopic representation
Brain Research, 1982A 'new' and orderly representation of the body surface was found in the cerebral cortex of the cat. This somatotopic map was located in the anterior ectosylvian sulcus (AES), an area known to represent several modalities, but believed to be distinguished from primary sensory cortex by its lack of sensory topographies.
