Effect of GABAB receptor blockade on receptive fields of raccoon somatosensory cortical neurons during reorganization

Single unit recordings were made in the fourth digit representation of raccoon somatosensory cortex after amputation of the fourth digit. The receptive fields of neurons in this “reorganized” cortex were studied before and after microiontophoretic application of a highly specific GABAB receptor antagonist, CGP 55845. When the recordings were performed early… (More)
