Document Summary

Hindbrain: reticular formation (reticular activation system)- responsible for general arousal and sleep, acts as a light switch for the rest of the brain. Damage to the cerebellum can cause problems to motor coordination, balance, accuracy of picking up objects, etc. Long-term alcoholism can cause these long-term damages: medulla- regulates blood pressure, heart rate, breathing, reflexes, monitoring of the chemical composition of the blood (ex: vomiting reflex); acts as an internal life support system. Amydala- responsible for emotion; a patient with damage to this area may appear to be very monotone or bland. Hippocampus- starts at amydala and forms around the thalamus; plays a role in memory: corpus callosum- connects the left and right brain and allows them to communicate with one another. Damage to the right parietal lobe results in hemineglect, in which the affected patient completely ignores the left side of their body: frontal lobe. Motor cortex- allowing for fine motor movements (ex: playing an instrument)
