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. Provide myelin in central nervous system






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






3. Measures oxygen flow in different brain areas - used most in cognitive psych to measure activity in different brain regions during certain tasks






4. A type of cell that help support neurons; oligodendrocytes and Schwann cells






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






6. Connections between brain and spine






7. Bundles of axon - Nerve fiber






8. Of cerebral cortex - responsible for somatosensory system






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






10. Incredible rage easily provoked when cerebral cortex is removed






11. Organizational and activational






12. Of diencephalon - channels sensory information to cerebral cortex






13. (1) resting potential - neuron negatively charged - cell membrane does not let ions in; (2) presynaptic cell releases neurotransmitters from terminal buttons; (3) postsynaptic receptors in postsynaptic cells detects neurotransmitter and open ion chan






14. Stage 1 & 2 non-REM sleep (with sleep spindles) - lower-amplitude and slower frequency waves






15. Overeating with no satiation of hunger; leads to obesity; damage to ventromedial region of hypothalamus






16. Decrease effects of a neurotransmitter (e.g. botox is an acetylecholine antagonist that decreases muscle activity)






17. Dysfunction in certain cortical association area - inability to write






18. 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






19. Released at neuromuscular junction to cause contraction of skeletal muscles - also involved in parasympathetic nervous system






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






21. An amino acid - most abundant excitatory neurotransmitter.






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






23. 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)

24. 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






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






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






27. Inactivated state of a neuron






28. PNS - interacts with internal environment - - Responsible for the 'fight or flight' response - - It controls the involuntary functions including movement of smooth muscles - digestion - blood circulation - breathing






29. Stage 3 (less sleep spindles) & 4 non-REM sleep - high-amplitude and low-frequency - deepest level of sleep






30. Associated with changes in hormone levels throughout the month - estradiol - progesterone - luteinizing hormone - follicle stimulating hormone






31. Increase in males during puberty causes genitals to matures and secondary sex characteristics to develop - example: testosterone






32. Extension of the spine - developed from base to the front






33. For female - the onset of the menstrual cycles - occurs during puberty






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






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






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






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






38. 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






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






40. Aka cell body. largest central portion - and make up gray matter - has a nucleus that directs neuron'S activity






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






42. Made up of sympathetic nervous system and parasympathetic nervous system






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






44. Increase in female during puberty causes genitals to matures and secondary sex characteristics to develop






45. Contain synaptic vessels that hold neurotransmitters






46. PNS fibers that run away from CNS (to cause effect the brain wants)






47. 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






48. Time after absolute refractory period - neuron can fire but needs a much stronger stimulus






49. Stage 0 & 1 non-REM sleep - low-amplitude and fast-frequency waves






50. 16 hours of sleep a day - 6 hours
