Stimulation-dependent changes in synaptic effects on unit activity of medial preoptic nucleus neurones in rats.
Stimulation-dependent changes in synaptic effects were observed in medial preoptic nucleus neurones during stimulation of the amygdala or pyriform cortex in anaesthetized female rats. The changes occurred after 35--240 triple pulse stimuli repeated at 0.89 Hz. Median eminence stimulation did not produce any synaptic change. These data show the existence of synaptic plasticity in the neural pathway from the amygdala and pyriform cortex to the medial preoptic nucleus.
