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. Control large voluntary muscle movements - Their degeneration is related to motor dysfunction in Parkinson'S and Huntington'S






2. 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






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






4. Chemicals that stimulate nearby cells






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






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






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






8. Midbrain; contains tectum and tegmentum






9. Inactivated state of a neuron






10. Present in fast-acting - directed synapses






11. Fissures seen on cortex surface






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






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






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






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






16. Gray matter - white matter






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






18. Dysfunction in certain cortical association area - difficulty processing sensory information






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






20. 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






21. Bumps on the brainstem - controls visual reflexes






22. Beginning of neuron (dendrites)






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






24. Controlled by hypothalamus - regulation of hormones in the body - The 'master gland' of the endocrine/hormone system






25. Organizational and activational






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






27. Low-amplitude and fast -frequency alpha waves






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






29. Made of thalamus and hypothalamus






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






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






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






33. Of cerebral cortex - responsible for vision






34. 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






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






36. Bundles of axon - Nerve fiber






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






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






39. Include serotonin - lack of serotonin is linked with depression






40. Occurs when people deprived of REM sleep - compensate by spending more time in REM sleep later in the night






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






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






43. An amino acid - most abundant inhibitory neurotransmitter






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






45. Of pituitary - activates thyroid






46. Contain synaptic vessels that hold neurotransmitters






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






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






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






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