Inhibition of a CeM output neuron by pre-stimulation
of mPFC in the cat. (A) BL stimulation activated this
CeM output neuron at a latency of approximately 7 ms.
Pre-stimulation of ipsilateral mPFC eliminated synaptic
responses to BL stimulation. Interval between mPFC and
BL stimuli is indicated on the left. (B) Graph plotting
responsiveness to BL stimuli (y-axis) as a function of
mPFC-BL ISIs (x-axis). Responsiveness was calculated
from 20 trials at each ISI. The inhibitory effect of mPFC
stimulation lasted approximately 120 ms in this neuron.
