7590096368Left HemisphereAnalytic thought, reasoning, logic, language, writing and number skills0
7590096369Right HemisphereArt awareness, intuition, creativity, memory, imagination, insight, music awareness1
7590100428CNSSpinal cord and the brain2
7590100429PNSNerves; sends signals to CNS3
7590104481HindbrainAt the base of the brain near the back of the skull; made up of the brainstem and the cerebellum. It controls vital activities over which we have no conscious control: heart rate, breathing, sleeping, and reflex actions.4
7590109641MidbrainSits on top of the brainstem under the cerebral hemispheres. It receives messages and sends them on to higher brain regions that deal with hearing, seeing, tasting and touching. It also receives replies that it directs to places such as the cerebellum.5
7590109642ForebrainThe most highly developed and largest part of the brain. It plays a major role in how we think, feel and behave.6
7590115091Corpus CallosumAllows messages to be sent from one side to the other7
7590118273CerebrumLargest part of the brain, separated into two hemispheres8
7590118274CerebellumPerception of time and modulating emotions, non-verbal communication9
7590122847Cerebral Cortexouter layer of grey matter making up the superficial aspect of the cerebrum (squiggles)10
7590125731ThalamusSensory station (except smell)11
7590125732HypothalamusControls pituitary gland and controls temperature12
7590130294The Three FissuresLongitudinal, Transverse and Lateral13
7590130295Frontal lobeMemory formation Emotions Decision making/reasoning Personality14
7590134281Parietal lobeResponsible for bodily sensations e.g. temperature and touch. Located deep to the parietal bone of the skull15
7590139779Occipital lobeResponsible for vision or seeing16
7590139912Temporal lobeAssociated with speech and hearing Language comprehension Information retrieval - memories17
7590153473What brain imaging techniques are there?fMRI - measures oxygen and function PET scan - measures glucose MRI - measures body tissue for the detection of tumours EEG - measures brain waves CAT scan - x-ray18
7590160830What are the benefits of exercise?Exercise halves the risks of heart attacks and adds two years to life expectancy and makes us feel happier. Exercise strengthens the heart, increasing blood flow and lowering blood pressure and the blood pressure reaction to stress Exercise provides the mastery experiences that help promote perceived ability to cope with depression Exercise increases the production of mood-boosting neurotransmitters such as noradrenaline, serotonin and endorphins.19
7590160831What are endorphins?Morphine-like substance that boosts mood20
7590168796What are the three classifications of drugs? Give examples.Hallucinogen - marijuana Depressant - alcohol Stimulant - ecstacy21
7590173836Psychological vs. Physiological responseOne physical one mental22
7590178285What is addiction?A circuit23
7590216744Somatic nervous systemregulates, monitors, processes and guides other nervous system activity24
7590236328What is Broca's area and where is it located?Frontal lobe. It controls facial neurons, speech, language comprehension. Broca's Aphasia - results in the ability to comprehend speech, but the decreased motor ability (or inability) to speak and form words.25
7590243301What is Wernicke's area and where is it located?Wernicke's area - language comprehension on the LEFT in the temporal and parietal lobes. Werknicke's Aphrasia - can speak but can't interpret info26
7590249430What is the reticular formation and what is its role?Pain signals from lower body reach cerebral cortex. Nerve fibres act to block the transmission of some pain signals to the brain. Assists in regulation of the sleep cycle and detecting sensory salience27
7590258377Name three hindbrain structures and describe their purposes.Medulla - automatically controls beating of heart, breathing Pons - helps coordinate other automatic functions and relays messages Cerebellum - Non-verbal communication, perception of time, regulation of emotions28
7590258378Split brain studyCut corpus callosum29
7590261699Franz GallPhrenology30
7590261700Phineas GageRod through frontal lobe and cheekbone31
