2
Q
Involvement (3 points)
A
-orienting movements
-processing visual, auditory and tactile sensory information (senses)

3
Q
Reticular information
A
-Screens incoming information
-Alerts higher brain centres to important information
-Regulates arousal and alertness
4
Q
Reticular Activating System (RAS)
A
-Extends in many different directions to parts of the cerebral cortex
-Regulates arousal by either increasing or dampening activity (e.g. - RAS is less active when we go to sleep)
-Influences what we pay attention to by ‘highlighting’ information of potential importance
