Document Summary

Stimulates the release of dopamine by blocking a gaba modulator. Binds with receptors for ach, 5-ht, and gaba. Gaba prolongs the opening of cl- channels, reducing activity in post synaptic membrane. Amphetamine last a while and then crash. Synapses on the order of 10 to 100 trillion. White matter = axons and dendrites millions of them. Grey matter = neurons, about 100 billion in top portion of the cortex. Cortex is folded in order to allow more volume in brain. Cortex big chunk of tissue on top, what makes us human. Corpus callosum connects the two hemispheres of the brain so that they can communicate. The old brain was the spinal cord swelling into a bunch of other structures. Medulla (vital signs, reflexes) pons (timing of cycles, daily rhythms) midbrain thalamus. Cerebellum wrapped around brain secondary processing area a lot of movement and fine- tuned activity and things that require a second processor.
