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






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






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






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






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






6. Dysfunction in certain cortical association area - inability to read






7. 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






8. Of cerebral cortex - responsible for vision






9. An amino acid - most abundant inhibitory neurotransmitter






10. Contain synaptic vessels that hold neurotransmitters






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






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






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






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






15. Provide myelin in central nervous system






16. 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






17. 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






18. Chemicals that stimulate nearby cells






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






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






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






22. Organizational and activational






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






24. PNS fibers that run towards CNS






25. Comprise two classes of neurotransmitters - indolamines and catecholamines






26. Made of thalamus and hypothalamus






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






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






29. Of diencephalon - channels sensory information to cerebral cortex






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






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






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






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






34. Consists of myelencephalon - metencephalon - and reticular formation






35. Divided into diencephalon and telencephalon






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






37. Of cerebral cortex - responsible for hearing - also Wernicke'S area (related to speech)






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






39. Gray matter - white matter






40. Of Hindbrain - aka medulla; Mainly controls for reflexes - but also controls sleep - attention - movement






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






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






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






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






45. Present in fast-acting - directed synapses






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






47. Of mesencephalon - vision and hearing






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






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