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






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






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






4. Chemicals that stimulate nearby cells






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






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






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






8. Provide myelin in central nervous system






9. comprises 50% of total sleep at birth - decreases to 25% - 20% sleep time spent in this type of sleep - Interspersed with non-REM every 30-40min - where dreams are experience - characterized by neural desynchrony - also known as paradoxical sleep -->






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






11. Bumps seen on cortex surface






12. Made up of sympathetic nervous system and parasympathetic nervous system






13. Where soma and axon connect






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






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






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






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






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






19. End of a neuron (terminal buttons)






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






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






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






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






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






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






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






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






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






29. Incredible rage easily provoked when cerebral cortex is removed






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






31. 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






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






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






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






35. Divided into diencephalon and telencephalon






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






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






38. Dysfunction in certain cortical association area - language disorder from damage to Wernicke'S area - in left temporal lobe; can speak but doesn'T understand how to correctly choose words (fluent but nonsensical)

39. 16 hours of sleep a day - 6 hours






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






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






42. An amino acid - most abundant inhibitory neurotransmitter






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






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






45. Between myelin sheath - help send impulse down axon






46. Of diencephalon - channels sensory information to cerebral cortex






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






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






49. Comprise two classes of neurotransmitters - indolamines and catecholamines






50. 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
