Q

Give an example of brain activity in action- Scenario: Deciding whether or not to cross a bust street.

A
  1. Brain activity:
    Sensory info from your eyes is processed, your brain assesses the risks, and you recall past experiences of crossing streets safely or not
  2. Thinking:
    You deliberate, weighing the risks and benefits, and decide its safe to cross
  3. Acting:
    The brain sends motor commands to your legs tp step forward, while constantly updating your movement based on new sensory feedback
  4. Feedback:
    If you safely cross you may feel relief and satisfaction. If you almost get hit, your brain quickly processes the situation, adjusting future behaviour to avoid risk.
