Abstract
Following innocuous changes in somatosensory experience at maturity, modifications of thalamic, thalamocortical and intracortical synaptic relays may contribute to receptive field plasticity of S1 cortex. We have investigated these separate aspects of reorganisation in the barrel cortex and the barreloid (Vpm) thalamus of adult rats following 3 to 30 days of cutting all but two whiskers unilaterally. Statistical analysis of changes in spatio-temporal features of responses in homologous barrel and barreloid neuronal populations reveal the degree by which use-dependent modifications in the thalamic relay contribute to processing of sensory information at the cortical level. These features will be discussed in relationship to models for experience-dependent reorganisation of somatosensory cortical maps.
