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






2. Neuron branches - receive impulses - branching patterns change throughout life






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






4. 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






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






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






7. Incredible rage easily provoked when cerebral cortex is removed






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






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






10. Comprise two classes of neurotransmitters - indolamines and catecholamines






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






12. PNS fibers that run towards CNS






13. Gray matter - white matter






14. Provide myelin in central nervous system






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






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






17. Chemicals that stimulate nearby cells






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






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






20. Divided into diencephalon and telencephalon






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






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






23. Of pituitary - activates thyroid






24. Contain synaptic vessels that hold neurotransmitters






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






26. Anytime during adulthood - short periods - often transient or reversible (current/recent circulation); - menstrual cycle (estradiol - progesterone - luteinizing hormone (LH) - follicle stimulating hormone (FSH)); - LH and FSH in females regulate ovum






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






28. Connections between brain and spine






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






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






31. An amino acid - most abundant inhibitory neurotransmitter






32. Midbrain; contains tectum and tegmentum






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






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






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






36. Consists of myelencephalon - metencephalon - and reticular formation






37. Presence during development causes a fetus to develop into a male (absence cause the fetus to develop into a female)






38. 16 hours of sleep a day - 6 hours






39. Between myelin sheath - help send impulse down axon






40. Outer half-inch of cerebral hemispheres; - sensory and intellectual functions; - split into frontal - occipital - parietal - temporal lobes; - 90% is neocortex (new in evolution - 6 layers cortex) - 10% < 6 layers and more primitive






41. Fissures seen on cortex surface






42. 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






43. Bumps seen on cortex surface






44. Bumps on the brainstem - controls auditory reflexes






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






46. 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)


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






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






49. Of mesencephalon - vision and hearing






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