About the brain


Changes in a person's behaviour can be a sign of damage to the brain.  Below are descriptions of each area of the brain, its function and how damage can cause specific changes.


Limbic System:

  • Affected early in Alzheimer's disease
  • Involved with memory and emotion
  • Links the lobes of the brain, enabling them to connect behaviour with memories
  • Controls emotion and basic needs, such as sleeping and eating

Hippocampus and temporal lobes:

  • The hippocampus processes verbal and visual memory. Verbal memories relate to what we read, say or hear; visual memory lets us recognize objects, faces and places to guide us around our environment.
  • Temporal lobes control new learning and short-term memory.

Parietal Lobes:

  • Help us sequence actions, such as getting dressed in the right order or starting and driving a car
  • Control our ability to understand spatial information, such as our location in a specific environment and where other objects are

Frontal Lobe:

  • Initiates activity and lets us plan and organize our actions
  • Regulates social judgment and behavior, such as knowing appropriate behaviour for a situation, interpreting others feelings and monitoring our actions

Occipital Lobe:

  • Controls vision and the ability to see and combine colours, shapes, angles and movement into meaningful patterns
