Cortical Association Areas-prefrontal assoc. cortex: piece of brain that allows you to know the consequencesThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute. removes personality when taken out tranquilizers: psychologist can talk to patients who are paranoid; allows patients to be rendered calm-parietal-temporal-occipital assoc. cortex: piece of brain that allows you to integrate sensory information from different sources lesions in this area (bird singing, hear it, but where is it coming from?)-limbic assoc. areas: in temporal lobes; higher functions related to cerebellum-Subcortical structures:o basal nuclei: inhibitory input Ex.) muscles cannot relax, tremor, Parkinson’s Disease “resting tremor”o thalamus: all sensory information passes o hypothalamus: link b/w nervous system and endocrine systemo control of fluid content, food intake, rate of water loss, body temp., autonomic systemo emotions arise here limbic system: includes pieces of other parts of the brain, controls learning and motivation; emotional inputII. Memory: storage of information-short term: few seconds to few minutes; to learn same thing, have to start over; limitedcapacity-consolidation: converting short-term to long-term memory-long-term: lasts from a long time to lifetime; virtually unlimited capacity III. Amnesia: loss of memory-retrograde amnesia: blow in the head and unable to recall what happened at the time of impact-anterograde amnesia: inability to consolidate short-term to long-term memory cannot form new memories, but remembers the pastIV. Cerebellum-allows us to coordinate sequential acts-normal posture, walking, playing musical instruments-lesions in this area cause movement problems intentional tremor: tremble when changing direction; stops with strong movement; inability to do activity smoothly when changing direction RECALL: in the basal nuclei, we have the resting tremorV. Brain Stem: connects cerebellum and cerebrum-controls number of body functions like gastral intestinal activity, heart rate, respiration, etc..VI. Reticular Formation-network in the brain stem through which all sensory information has to pass -Activating system: controls states of neuralgia1) extreme alert2) awake (wakefulness)3) sleep4)
