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






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






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






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






5. Of diencephalon - controls autonomic nervous system biological motivations (hunger - thirst) and pituitary gland






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






7. Provide myelin in central nervous system






8. Made up of somatic nervous system and autonomic nervous system






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






10. Bumps seen on cortex surface






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






12. Midbrain; contains tectum and tegmentum






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






14. Of pituitary - activates thyroid






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






16. 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






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






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






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






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






21. Where soma and axon connect






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






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






24. Connections between brain and spine






25. Holds neurotransmitters






26. 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)

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






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






29. Inactivated state of a neuron






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






31. 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






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






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






34. 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






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






36. 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






37. Made up of brain and spinal cord






38. An amino acid - most abundant inhibitory neurotransmitter






39. End of a neuron (terminal buttons)






40. Low-amplitude and fast -frequency alpha waves






41. Gray matter - white matter






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






43. Provide myelin in peripheral nervous system






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






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






46. Beginning of neuron (dendrites)






47. Organizational and activational






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






49. Bundles of axon - Nerve fiber






50. Chemicals that stimulate nearby cells
