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. Contain synaptic vessels that hold neurotransmitters






2. 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






3. PNS fibers that run towards CNS






4. Connections between brain and spine






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






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






7. Changes in a nerve cell'S charge as the result of stimulation - 2 forms: excitatory postsynaptic potential and inhibitory postsynaptic potential






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






9. Inner core of spine - cell bodies and dendrites






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






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






12. Gray matter - white matter






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






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






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






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






17. 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






18. Comprise two classes of neurotransmitters - indolamines and catecholamines






19. Holds neurotransmitters






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






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






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






23. Provide myelin in central nervous system






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






25. Positron emission tomography - scans glucose metabolism to measure activity in various brain regions






26. 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






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






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






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






30. Organizational and activational






31. Of cerebral cortex - responsible for vision






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






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






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






35. Provide myelin in peripheral nervous system






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






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






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






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






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






41. Consists of myelencephalon - metencephalon - and reticular formation






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






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






44. Incredible rage easily provoked when cerebral cortex is removed






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






46. Low-amplitude and fast -frequency alpha waves






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






48. 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






49. Of diencephalon - channels sensory information to cerebral cortex






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