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. Bumps on the brainstem - controls visual reflexes






2. Provide myelin in peripheral nervous system






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






4. 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)


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






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






7. Beginning of neuron (dendrites)






8. Present in fast-acting - directed synapses






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






10. 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






11. 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






12. Made up of brain and spinal cord






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






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






15. Inactivated state of a neuron






16. Midbrain; contains tectum and tegmentum






17. 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






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






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






20. Of cerebral cortex - responsible for somatosensory system






21. Bumps on the brainstem - controls auditory reflexes






22. Where soma and axon connect






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






24. Organizational and activational






25. 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






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






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






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






30. 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






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






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






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






34. 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)


35. Between myelin sheath - help send impulse down axon






36. Outer covering of spine - nerve fibers - axon bundles - myelin sheathing






37. Inner core of spine - cell bodies and dendrites






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






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






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






41. Increase effects of a neurotransmitter (e.g. selective serotonin reuptake inhibitors [for depression] increase serotonin activity)






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






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






44. Holds neurotransmitters






45. 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






46. Comprise two classes of neurotransmitters - indolamines and catecholamines






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






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






49. Incredible rage easily provoked when cerebral cortex is removed






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