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. 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)

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






3. Comprise two classes of neurotransmitters - indolamines and catecholamines






4. Chemicals that stimulate nearby cells






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






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






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






8. Provide myelin in peripheral nervous system






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






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






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






12. 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






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






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






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






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






17. PNS fibers that run towards CNS






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






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






20. Low-amplitude and fast -frequency alpha waves






21. 16 hours of sleep a day - 6 hours






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






23. Beginning of neuron (dendrites)






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






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






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






27. Inactivated state of a neuron






28. End of a neuron (terminal buttons)






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






30. Occur during specific periods in development - permanent or long-lasting effects; - presence of H-Y antigen in development causes fetus to develop into a male - absence to female; - androgens in males and estrogen in females causes secondary sex cha






31. An amino acid - most abundant excitatory neurotransmitter.






32. Bumps on the brainstem - controls auditory reflexes






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






34. Of mesencephalon - vision and hearing






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






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






37. Of cerebral cortex - responsible for hearing - also Wernicke'S area (related to speech)






38. Of pituitary - activates thyroid






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






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






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






42. Bumps seen on cortex surface






43. Consists of myelencephalon - metencephalon - and reticular formation






44. 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






45. 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






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






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






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






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






50. 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
