| A | B |
| Hypothalamus | involved in regulating organism's homeostasis. Has role in many motivated behaviors: sleep, drink, sex, aggr, maternal, appetite, emotions, temp. |
| Cerebral Cortex | covers entire brain, 2 hemispheres, bilaterally symmetrical, mediates most higher cog processes. 4 lobes: Frontal, parietal, temporal, occipital. |
| Thalamus | Central switching station for sensory info to cortex, comm's betw diff cortical regions, & cortex and subcortical regions. No smell. |
| Amygdala | Substructure of the limbic sx, involved in control of emo. activities, attachment of emotions to sensory stimuli |
| Basal Ganglia | group of midbrain structures involved in muscle tone and motor coordination & posture. Pt. of extrapyramidal motor sx. |
| Cerebellum | Brain center, involved in coord. of mvmts of diff. pts of the body; involved in coord'ing well-learned fine motor movements |
| Corpus Callosum | Bundle of nerve fibres that connect the l and r cerebral hemispheres. |
| Frontal Lobe | lobe of cerebral hemisphere, contains the motor cortex and is involved w/expressive lang and variety of motivational & personality functions |
| Limbic System | Integrated sx of mid & lower brain centers involving the organisms basic emotional & motivations life. Includes: amygdala, septum & hippocampus |
| Medulla | Hindbrain str involved in mediation of vital autonomic activites: heart rate, bp, respiration |
| Occitital Lobe | Lobe of cerebral cortex containing visual cortex |
| Temporal Lobe | lobe in cerebral cortex that contains auditory cortex assoc'd w/ receptive lang, emotion & memory |
| Parietal Lobe | lobe of cerebral cortex, contains somatosensory cortex, involved in processing sensations (pain,temp, kinesthesia...) coording these with visual & other sensory stimuli. Damage: complex sensory/motor abnormalities that pt.s deny deficit in. |
| Hippocampus | In limbic sx, plays impt role in transferring information from short term - long term memory. |
| Broca's Area | Region in frontal pt of L hemisphere responsible for speech production. Damage: slow, laborious, non-fluent speech "expressive aphasia." |
| Wernicke's Area | Region in L temporal lobe involved in understanding speech. Damage; receptive or fluent speech apahsias. Speech is devoid of meaning, person isn't aware of problem. |
| Reticulating Activating System (RAS) | System of undifferentiated neurons extending throughout the brain, responsible for functions related to brain arousal, sleep, filtering stimuli, selective attention. |
| Brain Tumor | Specific location depends on tumor locations; sx: HA, siezures, focal neurological signs. |
| Left Hemisphere | Controls motor & sensory functions on R side of body. Specialized for verbal activities. |
| Right Hemisphere | Controls motor & sensory functions on L side of body. Specialized for spatial activities. |
| Storke | Neurological impairment due to sudden interference of blood flow to brain. Sx depend on area of brain affected. |
| Kluver-Bucy Syndrome | camage or removal of portions of temp. lobe & subcortical areas: decr recog of people, loss of fear and rage reaction, increase sex, mem. deficits. |
