Neural oscillations in the infralimbic cortex after electrical stimulation of the amygdala. Relevance to acute stress processing

This article is protected by copyright. All rights reserved. Interaction between the infralimbic region of the medial prefrontal cortex (IL) and the central nucleus of the amygdala (CeA) is critical in the stress processes. After the electrical activation of the CeA in urethane‐anesthetised rats, by mimicking firing rates induced by acute stress, a delayed particular slow wave in the IL local field potential, in association with theta, gamma and spindles oscillations, was observed. In addition, this slow oscillation was accompanied by an increase in theta‐gamma coupling. This characteristic oscillatory pattern might be a functional substrate to respond to stress and for memory formation.
