GRE Psychology: Physiological/behavioral Neuroscience 1

Subjects : gre, psychology
  • 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. Bumps on the brainstem - controls visual reflexes

2. Provide myelin in central nervous system

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

4. Of cerebral cortex - responsible for vision

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

6. 16 hours of sleep a day - 6 hours

7. 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)

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

9. Inactivated state of a neuron

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

11. Beginning of neuron (dendrites)

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

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

14. An amino acid - most abundant inhibitory neurotransmitter

15. Consists of myelencephalon - metencephalon - and reticular formation

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

17. Where soma and axon connect

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

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

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

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

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

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

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

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

26. 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

27. Provide myelin in peripheral nervous system

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

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

30. 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

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

32. Present in fast-acting - directed synapses

33. Bumps seen on cortex surface

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

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

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

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

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

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

40. Incredible rage easily provoked when cerebral cortex is removed

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

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

43. Bundles of axon - Nerve fiber

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

45. An amino acid - most abundant excitatory neurotransmitter.

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

47. PNS fibers that run towards CNS

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

49. Of pituitary - activates thyroid

50. Depolarization - + from outside allowed into cell - increase firing
