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 mesencephalon - vision and hearing






2. Bundles of axon - Nerve fiber






3. Present in fast-acting - directed synapses






4. Of pituitary - activates thyroid






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






6. Decrease effects of a neurotransmitter (e.g. botox is an acetylecholine antagonist that decreases muscle activity)






7. Made of thalamus and hypothalamus






8. 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






9. 16 hours of sleep a day - 6 hours






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






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






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






13. Contain synaptic vessels that hold neurotransmitters






14. PNS fibers that run away from CNS (to cause effect the brain wants)






15. PNS fibers that run towards CNS






16. Midbrain; contains tectum and tegmentum






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






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






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






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






21. Pathway that runs to and from CNS






22. 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






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






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






25. Of cerebral cortex - responsible for vision






26. An amino acid - most abundant inhibitory neurotransmitter






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






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






29. Made up of brain and spinal cord






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






31. Beginning of neuron (dendrites)






32. Holds neurotransmitters






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






34. Control large voluntary muscle movements - Their degeneration is related to motor dysfunction in Parkinson'S and Huntington'S






35. Bumps on the brainstem - controls visual reflexes






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






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






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






39. Organizational and activational






40. Inner core of spine - cell bodies and dendrites






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






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






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






44. 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






45. 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)

46. Bumps seen on cortex surface






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






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






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






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