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






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






3. Present in fast-acting - directed synapses






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






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






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






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






8. (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






9. Beginning of neuron (dendrites)






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






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






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






13. Chambers filled with cerebrospinal fluid that insulate brain from shock






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






15. Of diencephalon - controls autonomic nervous system biological motivations (hunger - thirst) and pituitary gland






16. Made up of brain and spinal cord






17. 16 hours of sleep a day - 6 hours






18. Of mesencephalon - vision and hearing






19. Associated with changes in hormone levels throughout the month - estradiol - progesterone - luteinizing hormone - follicle stimulating hormone






20. Of cerebral cortex - responsible for somatosensory system






21. 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






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






23. Contain synaptic vessels that hold neurotransmitters






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






25. 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






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






27. Holds neurotransmitters






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






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






30. Consists of myelencephalon - metencephalon - and reticular formation






31. Increase effects of a neurotransmitter (e.g. selective serotonin reuptake inhibitors [for depression] increase serotonin activity)






32. Pathway that runs to and from CNS






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






34. Of cerebral cortex - responsible for vision






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






36. Connections between brain and spine






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






38. Made of thalamus and hypothalamus






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






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






41. Bumps seen on cortex surface






42. 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






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






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






45. Aka cell body. largest central portion - and make up gray matter - has a nucleus that directs neuron'S activity






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






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






48. An amino acid - most abundant excitatory neurotransmitter.






49. 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






50. Bumps on the brainstem - controls auditory reflexes
