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






2. Comprise two classes of neurotransmitters - indolamines and catecholamines






3. Beginning of neuron (dendrites)






4. PNS fibers that run towards CNS






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






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






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






8. Chemicals that stimulate nearby cells






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






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






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






12. Holds neurotransmitters






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






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






15. Made of thalamus and hypothalamus






16. Bumps on the brainstem - controls visual reflexes






17. Incredible rage easily provoked when cerebral cortex is removed






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






19. 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






20. 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






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






22. Organizational and activational






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






24. Bumps seen on cortex surface






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






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






27. Inactivated state of a neuron






28. 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






29. Inner core of spine - cell bodies and dendrites






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






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






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






33. 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






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






35. An amino acid - most abundant excitatory neurotransmitter.






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






37. An amino acid - most abundant inhibitory neurotransmitter






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






39. Areas on cortex that correspond to certain functions; - the larger the area - the more sensitive and highly accessed the function - Damage to a particular area would result in certain dysfunction






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






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






42. Of telencephalon - links brain areas dealing with emotion and decisions






43. Associated with changes in hormone levels throughout the month - estradiol - progesterone - luteinizing hormone - follicle stimulating hormone






44. 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






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






46. Present in fast-acting - directed synapses






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






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






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






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