Regulation of Extinction-Related Plasticity by Opioid Receptors in the Ventrolateral Periaqueductal Gray Matter

Abstract

Recent work has led to a better understanding of the neural mechanisms underlying the extinction of Pavlovian fear conditioning. Long-term synaptic changes in the medial prefrontal cortex (mPFC) are critical for extinction learning, but very little is currently known about how the mPFC and other brain areas interact during extinction. The current study… (More)
