works in the squirrel monkey somatosensory thalamus. J Neuro-
physiol 84: 484­494, 2000. The somatosensory thalamus (here we
examine neurons in the caudal cutaneous portion of ventral posterior
lateral nucleus, VPL) is composed of a somatotopic arrangement of
anteroposteriorly oriented rods. Each rod is a collection of neurons
with homogeneous properties that relay sensory information to spe-
cific cortical columns. We developed a multi-electrode recording
