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 pituitary - regulate water levels in body and therefore BP






2. Present in fast-acting - directed synapses






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






4. Pathway that runs to and from CNS






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






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






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






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






9. 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






10. 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






11. In females - regulate the development of ovum and trigger ovulation - In males - regulate the development of sperm cells and the production of testosterone






12. Organizational and activational






13. Inner core of spine - cell bodies and dendrites






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






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






16. An amino acid - most abundant excitatory neurotransmitter.






17. Beginning of neuron (dendrites)






18. 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






19. Bumps seen on cortex surface






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






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






22. Chemicals that stimulate nearby cells






23. Connections between brain and spine






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






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






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






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






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






29. 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






30. Provide myelin in central nervous system






31. Of mesencephalon - vision and hearing






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






33. 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






34. Where soma and axon connect






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






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






37. Like neurotransmitters but cause long-term changes in postsynaptic cell






38. Of pituitary - activates thyroid






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






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






41. Fissures seen on cortex surface






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






43. Of diencephalon - channels sensory information to cerebral cortex






44. Divided into diencephalon and telencephalon






45. Contain synaptic vessels that hold neurotransmitters






46. Between myelin sheath - help send impulse down axon






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






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






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






50. Of cerebral cortex - responsible for somatosensory system
