Prefrontal associational area
In what area of the brain does this happen? You see the size and shape of a ball?
Primary visual cortex
In what area of the brain does this happen? You see the color and type of the ball.
Secondary visual cortex
In what area of the brain does this happen? You recognize that its a basketball.
Parietoassociational area
In what area of the brain does this happen? Memories of experiences with basketballs, emotions attached.
Occipitotemporal association (includes limbic system)
In what area of the brain does this happen? Decides how you are going to react when the basketball is thrown to you.
