Abstract

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.
