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. Of mesencephalon - vision and hearing






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






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






4. 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






5. An amino acid - most abundant inhibitory neurotransmitter






6. Made of thalamus and hypothalamus






7. Chemicals that stimulate nearby cells






8. 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






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






10. 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






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






12. 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)


13. 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






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






15. Extension of the spine - developed from base to the front






16. Pathway that runs to and from CNS






17. Bumps seen on cortex surface






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






19. Where soma and axon connect






20. 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






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






22. Provide myelin in central nervous system






23. Midbrain; contains tectum and tegmentum






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






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






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






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






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






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






30. Present in fast-acting - directed synapses






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






32. Of diencephalon - channels sensory information to cerebral cortex






33. Inner core of spine - cell bodies and dendrites






34. 16 hours of sleep a day - 6 hours






35. 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






36. Beginning of neuron (dendrites)






37. Between myelin sheath - help send impulse down axon






38. In females - regulate the development of ovum and trigger ovulation - In males - regulate the development of sperm cells and the production of testosterone






39. Connections between brain and spine






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






41. Bumps on the brainstem - controls auditory reflexes






42. Aka cell body. largest central portion - and make up gray matter - has a nucleus that directs neuron'S activity






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






44. Of cerebral cortex - responsible for somatosensory system






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






46. An amino acid - most abundant excitatory neurotransmitter.






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






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






49. Made up of brain and spinal cord






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