Distinct populations of NMDA receptors at subcortical and cortical inputs to principal cells of the lateral amygdala.

abstract：:1. Receptive fields (RFs) of neurons in the primary somatosensory (SI) cortex were defined before, during, and after electrical stimulation of myelinated fibers in the dorsal cutaneous branch of the ulnar nerve in adult pentobarbital sodium-anesthetized cats. 2. This stimulation resulted in an approximately threefold ...
