Major Brain Structures

A area that along with the midbrain make up the brain stem. WIthin it is the Medulla, Pons,Cerebellum, and the Reticular formation
Vital life functions. Where neural messages from each side of the body cross to the opposite side of the brain. Oxygen levels in blood,vomiting response, breathing.
The "bridge" of the brain for info to go from lower to higer brain structures. Interrupts motor messages during REM sleep.
Controls balance and corrdination. Smooth movement
Reticular formation
Alertness and attention. Individualzed,adaptive alarm system.
A small part of the brain above the pons that integrates sensory information and relays it upward. Contains Substantia Nigra.
Substantia Nigra
Literally means substance dark. Contains neurons that are rich in dopamine (link to Parkinson's).
The largest part of the brain, which holds the Cerebral cortex, Temperal lobe, Occipital lobe, Parietal lobe, Frontal lobe, Corpus callosum, Limbic system, Thalamus, Hypothalamus, Hippocampus, and the Amygdala.
Cerebral cortex
Outermost layer of brain tissue. Extremely sophisitcated, where conscious thought occures (Perception).
Temporal lobe
Process auditory data (sensation). Also contains Wernicke's area (left hemi only).
Wernicke's area
language comprehension
Occipital lobe
Processes visual data (sensation).
Parietal lobe
Processes body sensations (body temp,etc...). Contains the somatosensory cortex.
Frontal lobe
Where personality "lives". Planning, problem solving, consequences, emotions filter. Contains motoer cortex (for voluntary motor movement) and also the Broca's area (left hemi only).
Broca's area
Speech production
Corpus callosum
Band of axon fibers that connects the two hemispheres.
Limbic system
The limbic system is a set of brain structures including the Hippocampus, Amygdala, Thalamus, and the Hypothalamus.
Relay staion: receives and distributs information.
Links nervous and endocrine systems. Controls our circadian rhythms.
Handles formation of new memory.
Raw emotion.
