83: 3031–3041, 2000. Short-term synaptic plasticity, in particular short-term depression and facilitation, strongly influences neuronal activity in cerebral cortical circuits. We investigated short- term plasticity at excitatory synapses onto layer V pyramidal cells in the rat medial prefrontal cortex, a region whose synaptic dynamic.
Amygdala outflow is regulated, in part, by the prefrontal cortex. Medial prefrontal cortices, including the ACC and OFC, have reciprocal connections with the amygdala and are important in the inhibitory regulation of amygdalar function. Disruption of prefrontal efferents projecting to the amygdala result in unregulated.
