The Brain Stem and Cerebellum
• Thalamus• Pons• Cerebellum• Reticular Formation• Medulla• Brain Stem
Thalamus
• Top of the Brain Stem. • directs messages to the sensory receiving
areas in the cortex. • *Smell is the only sense that it DOES NOT go
through this structure.

The Brain Stem and Cerebellum
• Thalamus• Pons• Cerebellum• Reticular Formation• Medulla• Brain Stem
Pons
• Regulation of our states of wake/sleep cycle and dreaming.
• Acts as a bridge that connects the brain stem to the cerebellum

The Brain Stem and Cerebellum
• Thalamus• Pons• Cerebellum• Reticular Formation• Medulla• Brain Stem
Cerebellum
• Involved in our sense of balance and coordination of our muscles.
• If your cerebellum is damaged you would be exceedingly clumsy and uncoordinated.

The Brain Stem and Cerebellum
• Thalamus• Pons• Cerebellum• Reticular Formation• Medulla• Brain Stem
Medulla
• It controls basic life support functions like your heartbeat, blood pressure and breathing.
• Operates on “autopilot”

The Brain Stem and Cerebellum
• Thalamus• Pons• Cerebellum• Reticular Formation• Medulla• Brain Stem
Brain Stem
• Oldest part of the brain, includes the previous mentioned medulla, pons and the Reticular (formation) Activation System = arouses the cortex to keep the brain alert and attentive . Wakefulness/consciousness
