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






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






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






4. An amino acid - most abundant excitatory neurotransmitter.






5. Midbrain; contains tectum and tegmentum






6. Released from the pituitary and facilitates birth and breast feeding - also involved in pair bonding (mother to child or romantic partners) -






7. Inactivated state of a neuron






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






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






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






11. 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






12. End of a neuron (terminal buttons)






13. Bumps on the brainstem - controls auditory reflexes






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






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






17. Of diencephalon - channels sensory information to cerebral cortex






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






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






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






21. 16 hours of sleep a day - 6 hours






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






23. Divided into diencephalon and telencephalon






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






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






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






27. Incredible rage easily provoked when cerebral cortex is removed






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






29. Of cerebral cortex - responsible for vision






30. Made up of brain and spinal cord






31. Organizational and activational






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






33. PNS fibers that run towards CNS






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






35. 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






36. Bumps seen on cortex surface






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






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






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






40. 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






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






42. Jumping from one node of Ranvier to the next due to insulation by myelin sheath






43. Chemicals that stimulate nearby cells






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






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






46. Made of thalamus and hypothalamus






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






48. Inner core of spine - cell bodies and dendrites






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






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