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. Once minimum threshold is met - intensity always the same regardless of amount of stimulation






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






3. Holds neurotransmitters






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






5. Of cerebral cortex - responsible for somatosensory system






6. 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






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






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






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






10. 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






11. 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






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






13. Inactivated state of a neuron






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






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






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






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






18. Midbrain; contains tectum and tegmentum






19. An amino acid - most abundant inhibitory neurotransmitter






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






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






22. Bumps on the brainstem - controls visual reflexes






23. Made up of brain and spinal cord






24. Fissures seen on cortex surface






25. Connections between brain and spine






26. Present in fast-acting - directed synapses






27. 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






28. Low-amplitude and fast -frequency alpha waves






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






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






31. Of pituitary - activates thyroid






32. 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






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






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






35. Of mesencephalon - vision and hearing






36. Gray matter - white matter






37. Chemicals that stimulate nearby cells






38. Provide myelin in central nervous system






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






40. Areas on cortex that correspond to certain functions; - the larger the area - the more sensitive and highly accessed the function - Damage to a particular area would result in certain dysfunction






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






42. Incredible rage easily provoked when cerebral cortex is removed






43. An amino acid - most abundant excitatory neurotransmitter.






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






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






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






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






48. 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






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






50. 16 hours of sleep a day - 6 hours
