Im not exactly sure what the function of the various parts of the Brainstem are. Can you please go over exactly what the role of the Pons, Reticular Formation, Medulla, and Midbrain are?

Hindbrain: Reticular formation, medulla oblongata, cerebellum, pons

- Reticular formation: seratonin (neurotransmitter). Mood, appetite, sex, dreams
- Medulla oblongata: controls heart and lungs. Monitors oxygen.
- Cerebellum: balance, muscle activity.
- Pons: relay between medulla and thalamas.

Mid brain: inferior and superior colliculi. Also called tectums

- Superior: optic. Top of the brain
- Inferior: vestibular. Bottom of the brain.

Forebrain: thalamas, hypothalamus, limbic system, basal ganglia, cerebral cortex

- Thalamas: relay center for brain, most perception travels through here.
- Hypothalamus: 3 H. HOMEOSTASIS. HORMONES through HYPOPHOSPHEAL.
- Basal ganglia: same as dopamine (neurotransmitter); postural stability and smooths muscle movements

Limbic system: 4 components
- Septal nuclei - pleasure seeking
- Amygdala - fear and aggression
- Hippocampus - memory (explicit)
- Fornix - relay system for Limbic system ONLY
