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

2. PNS fibers that run towards CNS

3. 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

4. Anytime during adulthood - short periods - often transient or reversible (current/recent circulation); - menstrual cycle (estradiol - progesterone - luteinizing hormone (LH) - follicle stimulating hormone (FSH)); - LH and FSH in females regulate ovum

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

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

7. 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

8. Comprise two classes of neurotransmitters - indolamines and catecholamines

9. Where soma and axon connect

10. Connections between brain and spine

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

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

13. Gray matter - white matter

14. An amino acid - most abundant excitatory neurotransmitter.

15. Of mesencephalon - vision and hearing

16. Inactivated state of a neuron

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

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

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

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

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

22. Consists of limbic system - hippocampus - amygdala - cingulate gyrus

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

24. Pathway that runs to and from CNS

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

26. PNS - interacts with external environment by controlling voluntary movements of striated muscles

27. Hyperpolarization - + let out - - compared to outside - decrease firing

28. Bumps on the brainstem - controls visual reflexes

29. (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

30. Of cerebral cortex - responsible for somatosensory system

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

32. An amino acid - most abundant inhibitory neurotransmitter

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

34. Bundles of axon - Nerve fiber

35. 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

36. Of pituitary - stress hormone - increases androgen and cortisol production

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

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

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

40. Presence during development causes a fetus to develop into a male (absence cause the fetus to develop into a female)

41. Made up of brain and spinal cord

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

43. Of cerebral cortex - responsible for vision

44. Provide myelin in peripheral nervous system

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

46. Chemicals that stimulate nearby cells

47. Divided into diencephalon and telencephalon

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

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

50. 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)
