Personality traits localized to different areas of brain. Said you could determine traits by feeling the skull. Brain does NOT control personality characteristics.
Dr. Wilder Penfield and Electrical Brain Stimulation
Localization of Function supported. Different points of stimulation produced different responses.
"Little brain." Execution; required initial learning, but becomes automatic. Sensitive to alcohol.
Visual and auditory reflexes; reflexive behavior. Sensitive to movement in periphery. Blindsightedness.
Occurs when people have damage to part of brain that processes visual images we're aware of. Cortical blindness; only blind consciously. Damage to occipital cortez/primary visual cortex.
Largest part of brain. Thalamus, Hypothalamus, Striatum, Limbic System, Amygdola, Cerebral Cortex.
Endocrine (hormone) glands; regulates certain behaviors and sends signals to Medulla. Regulates all hormones through control of pituitary glad, which is the master endocrine organ.
Deep Brain Stimulation
Treatment for Parkinson's Disease, not a cure. Electrodes placed in striatum.
Involved in memory function and emotional behavior. Can't learn anything new if you have Hippocampus damage.
Main functions of lobes
Occipital: vision, temporal: hearing, parietal: body sensations, frontal: memory
Primary auditory cortex. Processing sound, visual processing, and complex shape analysis.
Temporal lobe damage. Can speak clearly, but it is not understandable. Lost auditory vocabulary and meaning of words.
Perception of Color and Brightness
We can see same colors through any filter (like sunglasses or tinted windows).
Inability to recognize familiar human faces and self. Temporal lobe lesion (damage) and affects memory.
Occurs with people with amputations or nerve damage. Feels like pain is still in the area, even though limb is gone. Neurons that processed that area still survive, but neighboring regions start to spread and take over.
Perception of any sensory stimulus on the left side of the patient is ignored (right parietal lobe damage).
Damage to Broca's. Difficult to get words out; "telegraphic" speech. Only content words.
Iron from gun backfired and went through his cheek and out of his skull. Couldn't relate to people well; temperament changes. That part of frontal lobe is involved in memory function, executive function, and inhibition of limbic system.
Brain damage in one certain area, but quickly spreads and can spread to other side of brain. Can see images on right visual field because that side is controlled by left side of brain, but not opposite (not connected).
