Synaptic transmission from the supratrigeminal region to jaw-closing and jaw-opening motoneurons in developing rats.

abstract：:Stress-related alterations to the induction of hippocampal synaptic plasticity have been implicated in certain forms of psychiatric disorders. However, relatively little is known about such changes in other psychiatric disorders-related structures. We tested this possibility in one of such structures, the nucleus accu...
