PHIS 206 1st Edition Lecture 7 Outline of Last Lecture I Cellular Neurophysiology cont d A Neurons B Convergence C 4 Major Processes of CNS II Central Nervous System overview III Peripheral Nervous System IV Central Nervous System V Brain Protection VI Anatomy Outline of Current Lecture I Cortical Association Areas II Memory III Amnesia IV Cerebellum V Brain Stem connects cerebellum and cerebrum VI Reticular Formation Current Lecture I Cortical Association Areas prefrontal assoc cortex piece of brain that allows you to know the consequences These 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 system o control of fluid content food intake rate of water loss body temp autonomic system o emotions arise here limbic system includes pieces of other parts of the brain controls learning and motivation emotional input II Memory storage of information short term few seconds to few minutes to learn same thing have to start over limited capacity 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 past IV 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 tremor V 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 neuralgia 1 extreme alert 2 awake wakefulness 3 sleep 4 coma
