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






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






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






4. An amino acid - most abundant excitatory neurotransmitter.






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






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






7. Connections between brain and spine






8. Incredible rage easily provoked when cerebral cortex is removed






9. Fissures seen on cortex surface






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






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






12. Tough connective tissues that cover/protect brain and spinal cord






13. Positron emission tomography - scans glucose metabolism to measure activity in various brain regions






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






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






16. PNS fibers that run towards CNS






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






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






19. Of cerebral cortex - responsible for somatosensory system






20. 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 -->






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






22. Gray matter - white matter






23. Consists of myelencephalon - metencephalon - and reticular formation






24. 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)

25. 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






26. 16 hours of sleep a day - 6 hours






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






28. Made of thalamus and hypothalamus






29. Bumps on the brainstem - controls visual reflexes






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






31. 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






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






33. 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






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






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






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






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






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






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






40. Present in fast-acting - directed synapses






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






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






43. An amino acid - most abundant inhibitory neurotransmitter






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






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






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






47. ANS - controls arousal mechanisms (blood circulation - pupil dilation - threat and fear response) - Lie detector test relies on the premise -->lying activates the sympathetic nervous system and cause things like (increase heart rate - blood pressure






48. End of a neuron (terminal buttons)






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






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