Abstract

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.

摘要

在麻醉的雌性大鼠中，刺激杏仁核或梨状皮质时，视前内侧核神经元的突触效应出现了刺激依赖性变化。这些变化发生在以0.89Hz重复施加35 - 240次三脉冲刺激之后。正中隆起刺激未产生任何突触变化。这些数据表明从杏仁核和梨状皮质到视前内侧核的神经通路中存在突触可塑性。
