Science

  • The cerebral cortex is divided into four main lobes: frontal, parietal, occipital, and temporal, each responsible for different brain functions.
  • It plays a key role in sensory perception, motor function, reasoning, and language, making it crucial for human behavior.
  • Research shows that the thickness of the cortex can change with experiences, such as learning new skills or undergoing training.

Psychology

  • The cortex is vital in the formation of memories and the processing of emotions, influencing our daily actions and decisions.
  • Studies suggest that different areas of the cortex are responsible for different types of memory, like short-term and long-term.
  • Damage to specific cortex areas can lead to various cognitive disorders, highlighting its importance in mental health.

Pop Culture
