GRE Psychology: Physiological/behavioral Neuroscience 1

Subjects : gre, psychology
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Stage 0 & 1 non-REM sleep - low-amplitude and fast-frequency waves






2. Like neurotransmitters but cause long-term changes in postsynaptic cell






3. PNS - interacts with external environment by controlling voluntary movements of striated muscles






4. Include dopamine - lack of dopamine linked with Parkinson'S - excess dopamine is linked with schizophrenia - dopamine is also involved in feelings of reward and therefore addiction






5. Occurs when people deprived of REM sleep - compensate by spending more time in REM sleep later in the night






6. Of cerebral cortex - responsible for somatosensory system






7. Of pituitary - stress hormone - increases androgen and cortisol production






8. Of telencephalon - links brain areas dealing with emotion and decisions






9. Bumps on the brainstem - controls auditory reflexes






10. Contain synaptic vessels that hold neurotransmitters






11. Of mesencephalon - rest of reticular formation; Also involved in the sensorimotor system - analgesic effect of opiates






12. Dysfunction in certain cortical association area - language disorder from damage to Broca'S area - in left frontal lobe; can understand speech but has difficulty speaking (slow - laborious - omits words)

13. Fast frequency bursts of brain activity - inhibits processing to keep tranquil state






14. Anytime during adulthood - short periods - often transient or reversible (current/recent circulation); - menstrual cycle (estradiol - progesterone - luteinizing hormone (LH) - follicle stimulating hormone (FSH)); - LH and FSH in females regulate ovum






15. Incredible rage easily provoked when cerebral cortex is removed






16. Include serotonin - lack of serotonin is linked with depression






17. Positron emission tomography - scans glucose metabolism to measure activity in various brain regions






18. Of telencephalon - involves in memory- transfer STM into LTM - - new neurons can form in adult mammalian brain






19. Takes about half an hour; (0) prelude to sleep - neural synchrony; alpha waves; person is relaxed and drowsy - closes eye; (1) Eyes begin to roll. alpha waves give way to irregular theta waves; loses responsiveness to stimuli - experiences fleeting t






20. Of diencephalon - channels sensory information to cerebral cortex






21. End of a neuron (terminal buttons)






22. REM-sleep - low-amplitude and fast-frequency waves that characterize waking states






23. Fissures seen on cortex surface






24. Of diencephalon - controls autonomic nervous system biological motivations (hunger - thirst) and pituitary gland






25. Of cerebral cortex - responsible for vision






26. Changes in a nerve cell'S charge as the result of stimulation - 2 forms: excitatory postsynaptic potential and inhibitory postsynaptic potential






27. Linked to pleasure and analgesia; can be endogenous (opioid peptides) or exogenous (morphine or heroin) - Exogenous endorphine are highly addictive






28. Protects the brain by making it difficult for toxic substances to pass from the blood into the brain - since blood vessel cells in the brain are tightly packed






29. Used to implant electrodes into animals' brains in experiments






30. PNS fibers that run towards CNS






31. Of pituitary - regulate water levels in body and therefore BP






32. Once minimum threshold is met - intensity always the same regardless of amount of stimulation






33. Time after a neuron fires which it cannot respond to stimulation






34. Measures brain wave patterns and have made it possible to study waking and sleeping states






35. Released from the pituitary and facilitates birth and breast feeding - also involved in pair bonding (mother to child or romantic partners) -






36. Bundles of axon - Nerve fiber






37. Of telencephalon - controls emotional reactions such as fear and anger






38. Provide myelin in peripheral nervous system






39. Chemicals that stimulate nearby cells






40. Of pituitary - activates thyroid






41. Or just synapse - the space between 2 neurons where they communication






42. Outer half-inch of cerebral hemispheres; - sensory and intellectual functions; - split into frontal - occipital - parietal - temporal lobes; - 90% is neocortex (new in evolution - 6 layers cortex) - 10% < 6 layers and more primitive






43. ANS - recuperation after arousal (decrease HR - BP - respiration)






44. ANS - controls arousal mechanisms (blood circulation - pupil dilation - threat and fear response) - Lie detector test relies on the premise -->lying activates the sympathetic nervous system and cause things like (increase heart rate - blood pressure






45. An amino acid - most abundant excitatory neurotransmitter.






46. Process in which neural pathways are connected and then some die out (children go through these process)






47. Consists of limbic system - hippocampus - amygdala - cingulate gyrus






48. In females - regulate the development of ovum and trigger ovulation - In males - regulate the development of sperm cells and the production of testosterone






49. Connections between brain and spine






50. Chambers filled with cerebrospinal fluid that insulate brain from shock
