Comparison of odor receptive field plasticity in the rat olfactory bulb and anterior piriform cortex.

abstract：:1. We have examined the effects of iontophoresing specific antagonists to excitatory amino acid receptors on the visual responses of cells in lamina A or A1 of the cat's lateral geniculate nucleus (LGN). 2. Cells were classified as On- or Off-center, X or Y, and lagged or nonlagged. The effects of antagonists were stu...
