Natural Selection

A process by which organisms that are better adapted to their environment tend to survive and produce more offspring, a key mechanism of evolution.

Prefrontal Cortex

The front part of the frontal lobes of the brain, involved in complex behaviors including planning, personality expression, decision making, and moderating social behaviour.

Limbic System

An elaborate neural framework and circuits within the brain, positioned near the cortex's edge, that are key in controlling natural impulses and mood fluctuations. It oversees essential emotions like anger, joy, and fear, in addition to primal needs such as the pursuit of food, sexual satisfaction, power, and offspring care.

Medial Temporal Lobes

A critical region of the brain involved in the formation of new memories, spatial navigation, and the integration of sensory information.
