Abstract

1. Responsiveness within the hand region of the second somatosensory area of cortex (SII) was investigated in the marmoset monkey (Callithrix jacchus) in association with cooling-induced, reversible inactivation of the primary somatosensory area, SI. The aims were to determine whether thalamocortical systems in this primate species are organized according to a serial scheme in which tactile information is conveyed from the thalamus to SI and thence to SII as the next hierarchical level of processing and to establish whether primates are fundamentally different, in this respect, from mammals in which tactile information is conveyed in parallel from the thalamus to both SI and SII. 2. Inactivation of the SI had area was achieved when the temperature at the face of the silver cooling block over this SI region was lowered to < or = 13 degrees C. Inactivation was confirmed by abolition of the SI surface potential evoked by a brief tap stimulus to the hand and by the abolition of responsiveness in single SI neurons located beneath and around the edge of the block. 3. The effect of SI inactivation on SII-evoked potentials was investigated in 20 experiments by simultaneous recording of the SI- and SII-evoked potentials. The SII respons...Continue Reading

Barrel cortex

Here is the latest research on barrel cortex, a region of somatosensory and motor corticies in the brain, which are used by animals that rely on whiskers for world exploration.
