PonsPons

• Sends signals between the cerebrum and the cerebellum.

• Plays a role in sleep and in relaying sensory information (sight, taste, touch, sound, smell)

Reticular FormationReticular Formation• Takes some information from the

spinal cord and sends it to the brain.

• Also plays a critical role in arousal.• “The reticular formation has also

been traced as one of the sources for the introversion and extroversion character traits. Introverted people have been found to have a more easily stimulated reticular formation, resulting in a diminished desire to seek out stimulus. Extroverted people, however, have a less easily stimulated reticular formation, resulting in the need for more stimulation to maintain brain activity” Wikipedia
