Abstract

Long-term potentiation of supragranular field potentials was evoked following tetanic stimulation of the white matter in the auditory cortex of adult rats. LTP corresponded to potentiation in orthodromic firing of supragranular pyramidal neurons. The induction of LTP depended on the activation of NMDA receptors. LTP was larger in the auditory than the visual cortex.

摘要

在成年大鼠听觉皮层对白质进行强直刺激后，诱发了颗粒上层场电位的长期增强。长期增强对应于颗粒上层锥体神经元顺向冲动发放的增强。长期增强的诱导依赖于N-甲基-D-天冬氨酸（NMDA）受体的激活。听觉皮层中的长期增强比视觉皮层中的更大。
