Depression is a common, chronic, and debilitating syndrome, which involves dysregulation throughout the brain’s limbic circuitry. This presentation focuses on stable changes in gene expression within the circuitry that controls life-long vulnerability to different forms of stress and the induction of depression-related behavioral abnormalities in mouse models. This presentation also outlines the established transcriptional and chromatin regulation as important mechanisms underlying the ways in which a history of stress causes lasting changes in targeted limbic brain regions which result in depression-related behavioral abnormalities in vulnerable individuals. The long-term goal is to use these insights to develop improved diagnostic tests and treatments for depression and related syndromes.

Format

Recorded webinar, non-interactive, self-paced distance learning activity.

This presentation was recorded on April 20, 2021 at the 15th Annual Amygdala, Stress, and PTSD Conference: Stress and the Mind.

How to Earn Credit

Participants who wish to earn AMA PRA Category 1 Credit ™ or a certificate of participation may do so by completing all sections of the course including the evaluation. After evaluating the program, course participants will be provided with an opportunity to claim hours of participation and print an official CME certificate (physicians) or certificate of participation (non-physicians) showing the completion date and hours earned. 

Continuing Education Credit

The American Psychiatric Association (APA) is accredited by the Accreditation Council for Continuing Medical Education (ACCME) to provide continuing medical education for physicians. 

The APA designates this enduring CME activity for a maximum of 0.75 AMA PRA Category 1 Credits™. Physicians should claim only the credit commensurate with the extent of their participation in the activity.
