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






2. Holds neurotransmitters






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






4. PNS fibers that run towards CNS






5. 16 hours of sleep a day - 6 hours






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






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






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






9. Midbrain; contains tectum and tegmentum






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






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






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






13. Organizational and activational






14. Contain synaptic vessels that hold neurotransmitters






15. Bumps seen on cortex surface






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






17. 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)

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






19. Inner core of spine - cell bodies and dendrites






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






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






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






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






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






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






26. Low-amplitude and fast -frequency alpha waves






27. 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






28. An amino acid - most abundant inhibitory neurotransmitter






29. 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






30. 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






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






32. Comprise two classes of neurotransmitters - indolamines and catecholamines






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






34. Made up of brain and spinal cord






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






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






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






38. 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






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






40. Of mesencephalon - vision and hearing






41. Fatty - insulating sheath on some axons for faster conduction of axon impulses






42. Bundles of axon - Nerve fiber






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






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






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






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






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






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






49. Connections between brain and spine






50. Present in fast-acting - directed synapses
