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. 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






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






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






4. Controlled by hypothalamus - regulation of hormones in the body - The 'master gland' of the endocrine/hormone system






5. Positron emission tomography - scans glucose metabolism to measure activity in various brain regions






6. Consists of myelencephalon - metencephalon - and reticular formation






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






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






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






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






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






12. An amino acid - most abundant inhibitory neurotransmitter






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






14. Between myelin sheath - help send impulse down axon






15. 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






16. Where soma and axon connect






17. Low-amplitude and fast -frequency alpha waves






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






19. Midbrain; contains tectum and tegmentum






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






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






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






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






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






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






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






27. Present in fast-acting - directed synapses






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






29. Bumps on the brainstem - controls visual reflexes






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






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






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






33. Provide myelin in peripheral nervous system






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






35. Bumps seen on cortex surface






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






37. Of pituitary - activates thyroid






38. Fissures seen on cortex surface






39. Chemicals that stimulate nearby cells






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






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






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






43. Connections between brain and spine






44. Made of thalamus and hypothalamus






45. 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






46. Organizational and activational






47. Of cerebral cortex - responsible for somatosensory system






48. Bundles of axon - Nerve fiber






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






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