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






2. Made up of brain and spinal cord






3. Provide myelin in peripheral nervous system






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






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






6. PNS fibers that run towards CNS






7. 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






8. Comprise two classes of neurotransmitters - indolamines and catecholamines






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






10. Of mesencephalon - vision and hearing






11. Bundles of axon - Nerve fiber






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






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






14. End of a neuron (terminal buttons)






15. (1) resting potential - neuron negatively charged - cell membrane does not let ions in; (2) presynaptic cell releases neurotransmitters from terminal buttons; (3) postsynaptic receptors in postsynaptic cells detects neurotransmitter and open ion chan






16. Stage 1 & 2 non-REM sleep (with sleep spindles) - lower-amplitude and slower frequency waves






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






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






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






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






21. Holds neurotransmitters






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






23. Of diencephalon - channels sensory information to cerebral cortex






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






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






26. Or just synapse - the space between 2 neurons where they communication






27. Transmits impulses of neuron - bundles of these are nerve fibers (white matter); the wider nerve fiber - the faster its conduction






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






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






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 inhibitory neurotransmitter






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






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






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






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






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






38. Associated with changes in hormone levels throughout the month - estradiol - progesterone - luteinizing hormone - follicle stimulating hormone






39. 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)

40. Stage 0 & 1 non-REM sleep - low-amplitude and fast-frequency waves






41. Provide myelin in central nervous system






42. Of pituitary - activates thyroid






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






44. Fissures seen on cortex surface






45. Contain synaptic vessels that hold neurotransmitters






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






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






48. 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






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






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