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






2. 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)

3. Made of thalamus and hypothalamus






4. PNS fibers that run away from CNS (to cause effect the brain wants)






5. Inactivated state of a neuron






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






7. Include dopamine - lack of dopamine linked with Parkinson'S - excess dopamine is linked with schizophrenia - dopamine is also involved in feelings of reward and therefore addiction






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






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






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






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






12. 16 hours of sleep a day - 6 hours






13. 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)

14. Divided into diencephalon and telencephalon






15. Made up of brain and spinal cord






16. comprises 50% of total sleep at birth - decreases to 25% - 20% sleep time spent in this type of sleep - Interspersed with non-REM every 30-40min - where dreams are experience - characterized by neural desynchrony - also known as paradoxical sleep -->






17. 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






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






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






20. Bundles of axon - Nerve fiber






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






22. Incredible rage easily provoked when cerebral cortex is removed






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






24. Of diencephalon - channels sensory information to cerebral cortex






25. Of telencephalon - involves in memory- transfer STM into LTM - - new neurons can form in adult mammalian brain






26. Anytime during adulthood - short periods - often transient or reversible (current/recent circulation); - menstrual cycle (estradiol - progesterone - luteinizing hormone (LH) - follicle stimulating hormone (FSH)); - LH and FSH in females regulate ovum






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






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






29. 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






30. Low-amplitude and fast -frequency alpha waves






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






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






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






34. Chemicals that stimulate nearby cells






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






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






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






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






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






40. Bumps on the brainstem - controls auditory reflexes






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






42. Chambers filled with cerebrospinal fluid that insulate brain from shock






43. Provide myelin in central nervous system






44. An amino acid - most abundant inhibitory neurotransmitter






45. Where soma and axon connect






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






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






48. Fissures seen on cortex surface






49. 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






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