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






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






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






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






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






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






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






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






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






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






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






12. Where soma and axon connect






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






14. Of cerebral cortex - responsible for vision






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






16. Bumps on the brainstem - controls auditory reflexes






17. Incredible rage easily provoked when cerebral cortex is removed






18. Between myelin sheath - help send impulse down axon






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






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






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






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






23. Fissures seen on cortex surface






24. 16 hours of sleep a day - 6 hours






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






26. Made of thalamus and hypothalamus






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






28. 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






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






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






31. Bumps on the brainstem - controls visual reflexes






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






33. Inactivated state of a neuron






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






35. 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






36. Bundles of axon - Nerve fiber






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






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






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






40. 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)

Warning: Invalid argument supplied for foreach() in /var/www/html/basicversity.com/show_quiz.php on line 183


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






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






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






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






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






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






47. Made up of brain and spinal cord






48. 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






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






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