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. An amino acid - most abundant excitatory neurotransmitter.






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






3. Provide myelin in peripheral nervous system






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






5. Where soma and axon connect






6. Of cerebral cortex - responsible for somatosensory system






7. The basic unit of the nervous system - Consist of: Dentrites - cell body (soma) - axon hillock - axon - myelin sheath - nodes of Ranvier - Terminal buttons - cell membrane - synapse - glial cells






8. Bumps on the brainstem - controls auditory reflexes






9. Incredible rage easily provoked when cerebral cortex is removed






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






11. Bundles of axon - Nerve fiber






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






13. 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






14. Present in fast-acting - directed synapses






15. 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






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






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






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






19. Controlled by hypothalamus - regulation of hormones in the body - The 'master gland' of the endocrine/hormone system






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






21. Made of thalamus and hypothalamus






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






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






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






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






26. Transmits impulses of neuron - bundles of these are nerve fibers (white matter); the wider nerve fiber - the faster its conduction






27. PNS fibers that run towards CNS






28. Of cerebral cortex - responsible for vision






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






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






31. End of a neuron (terminal buttons)






32. Of diencephalon - channels sensory information to cerebral cortex






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






34. 16 hours of sleep a day - 6 hours






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






36. Occur during specific periods in development - permanent or long-lasting effects; - presence of H-Y antigen in development causes fetus to develop into a male - absence to female; - androgens in males and estrogen in females causes secondary sex cha






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






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






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






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






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






42. Inactivated state of a neuron






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






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






45. Jumping from one node of Ranvier to the next due to insulation by myelin sheath






46. Of pituitary - activates thyroid






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






48. Fissures seen on cortex surface






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






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