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. Fissures seen on cortex surface






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






3. 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






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






5. Connections between brain and spine






6. Hyperpolarization - + let out - - compared to outside - decrease firing






7. Holds neurotransmitters






8. Base in hindbrain - rest in midbrain; oldest brain area; Controls alertness - thirst - sleep - involuntary muscles (i.e. heart)






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






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






11. End of a neuron (terminal buttons)






12. The process after a neurotransmitter has done its job - it is reabsorbed by the presynaptic cell






13. Of mesencephalon - vision and hearing






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






15. Divided into diencephalon and telencephalon






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






17. Inactivated state of a neuron






18. Bumps seen on cortex surface






19. Organizational and activational






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






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






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






23. Control large voluntary muscle movements - Their degeneration is related to motor dysfunction in Parkinson'S and Huntington'S






24. 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






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






26. (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






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






28. Of cerebral cortex - responsible for vision






29. Of diencephalon - channels sensory information to cerebral cortex






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






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






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






33. Midbrain; contains tectum and tegmentum






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






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






36. Made up of brain and spinal cord






37. Provide myelin in peripheral nervous system






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






39. Gray matter - white matter






40. Beginning of neuron (dendrites)






41. 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






42. 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






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






44. Incredible rage easily provoked when cerebral cortex is removed






45. Of pituitary - activates thyroid






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






47. Dysfunction in certain cortical association area - difficulty processing sensory information






48. Of telencephalon - structures around the brainstem involved in 4Fs (fleeing - feeding - fighting - and fornicating)






49. Dysfunction in certain cortical association area - inability to organize movement






50. Provide myelin in central nervous system
