Body's Stress Response: Understanding General Adaptation Syndrome

This lecture covers the stress response in the body, focusing on the General Adaptation Syndrome introduced by Hans Selye. It explains the three phases of stress response: alarm reaction, stage of resistance, and stage of exhaustion. The concept of allostasis is also discussed, highlighting the continuous changes in response criteria. The lecture further explores allostatic load, the long-term effects of stress responses on brain architecture and systemic pathophysiology.
