Which structure is involved in memory, emotion and aggression?

• A. Hippocampus
• B. Amygdala
• C. Medulla
• D. Spinal Cord

Answer: (B)

The amygdala sits at the center of how we process emotion and how that emotion influences what we remember and how we react aggressively. It rapidly evaluates emotional significance, especially threats, and triggers arousal and autonomic responses through connections with the hypothalamus and brainstem. It also modulates memory by tagging emotionally charged events for stronger encoding, working with the hippocampus to store those memories more vividly. So, it links emotional experience with both memory and behavioral responses like aggression. The hippocampus handles neutral memory formation and context, but not the core emotional processing. The medulla governs basic life-sustaining functions, and the spinal cord mainly carries signals and mediates reflexes, not emotional processing.
