[Long-term potentiation of the neuronal activity in the motor cortex induced by simultaneous stimulation of the thalamus and somatosensory cortex in cats].
Long-lasting potentiation of the cat motor cortex units induced by tetanic stimulation of the VL + SCx led to an increase of the motor cortex unit discharge rate. The findings suggest that co-activation of cortico-cortical and thalamo-cortical afferents modifies neuronal activity of the motor cortex at the specific site which receives convergent sensory input from the thalamus and the somatosensory cortex.
