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






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






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






4. Consists of myelencephalon - metencephalon - and reticular formation






5. Released at neuromuscular junction to cause contraction of skeletal muscles - also involved in parasympathetic nervous system






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






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






8. Stage 1 & 2 non-REM sleep (with sleep spindles) - lower-amplitude and slower frequency waves






9. Holds neurotransmitters






10. 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






11. 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






12. 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






13. End of a neuron (terminal buttons)






14. 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






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






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






17. Bumps on the brainstem - controls auditory reflexes






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






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






20. Present in fast-acting - directed synapses






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






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






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






24. Of diencephalon - channels sensory information to cerebral cortex






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






26. 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






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






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






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






30. 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)

Warning: Invalid argument supplied for foreach() in /var/www/html/basicversity.com/show_quiz.php on line 183


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






32. Of cerebral cortex - responsible for vision






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






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






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






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






37. Where soma and axon connect






38. 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






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






40. 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






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






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






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






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






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






46. Provide myelin in peripheral nervous system






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






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






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






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