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. An amino acid - most abundant inhibitory neurotransmitter






2. 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






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






4. Include serotonin - lack of serotonin is linked with depression






5. Provide myelin in peripheral nervous system






6. 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






7. Low-amplitude and fast -frequency alpha waves






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






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






10. Where soma and axon connect






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






12. Made of thalamus and hypothalamus






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






14. Consists of myelencephalon - metencephalon - and reticular formation






15. 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






16. Of cerebral cortex - responsible for somatosensory system






17. Bumps on the brainstem - controls visual reflexes






18. Comprise two classes of neurotransmitters - indolamines and catecholamines






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






20. Chemicals that stimulate nearby cells






21. Holds neurotransmitters






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






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






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






25. Bumps seen on cortex surface






26. An amino acid - most abundant excitatory neurotransmitter.






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






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






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






30. Of mesencephalon - vision and hearing






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






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






33. 16 hours of sleep a day - 6 hours






34. Dysfunction in certain cortical association area - inability to write






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






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






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






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






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






40. Of cerebral cortex - responsible for vision






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






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






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






44. Beginning of neuron (dendrites)






45. Incredible rage easily provoked when cerebral cortex is removed






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






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






48. Made up of brain and spinal cord






49. (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






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