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






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






3. Of cerebral cortex - responsible for vision






4. Outer covering of spine - nerve fibers - axon bundles - myelin sheathing






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






6. 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)


7. Areas on cortex that correspond to certain functions; - the larger the area - the more sensitive and highly accessed the function - Damage to a particular area would result in certain dysfunction






8. Neuron branches - receive impulses - branching patterns change throughout life






9. 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






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






11. Tough connective tissues that cover/protect brain and spinal cord






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






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






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






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






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






17. Dysfunction in certain cortical association area - language disorder from damage to Wernicke'S area - in left temporal lobe; can speak but doesn'T understand how to correctly choose words (fluent but nonsensical)


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






19. 4-6 complete ones - each about 90 minutes - early in the night most time in stage 3 and 4 - 2 and REM sleep predominate later






20. Made up of somatic nervous system and autonomic nervous system






21. Consists of myelencephalon - metencephalon - and reticular formation






22. Covers whole neuron - selective permeability - sometimes lets ions (positive charge) through






23. 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






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






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






26. Of mesencephalon - vision and hearing






27. Provide myelin in peripheral nervous system






28. Of cerebral cortex - controls speech (Broca'S area) - reasoning - problem solving






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






30. Chemicals that stimulate nearby cells






31. (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






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






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






34. Of hindbrain - has pons(connects brain parts to spine) and cerebellum(controls muscle coordination - balance - posture)






35. Present in fast-acting - directed synapses






36. Depolarization - + from outside allowed into cell - increase firing






37. Provide myelin in central nervous system






38. 16 hours of sleep a day - 6 hours






39. Bumps on the brainstem - controls visual reflexes






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






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






42. Pathway that runs to and from CNS






43. Made of thalamus and hypothalamus






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






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






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






47. Where soma and axon connect






48. Presence during development causes a fetus to develop into a male (absence cause the fetus to develop into a female)






49. An amino acid - most abundant inhibitory neurotransmitter






50. Of cerebral cortex - responsible for somatosensory system
