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. Include serotonin - lack of serotonin is linked with depression






2. 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)

Warning: Invalid argument supplied for foreach() in /var/www/html/basicversity.com/show_quiz.php on line 183


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






4. Of diencephalon - channels sensory information to cerebral cortex






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






6. Divided into diencephalon and telencephalon






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






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






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






10. 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






11. 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






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






13. Made up of brain and spinal cord






14. Of cerebral cortex - responsible for somatosensory system






15. Fissures seen on cortex surface






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






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






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






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






20. Inactivated state of a neuron






21. PNS fibers that run towards CNS






22. Bumps seen on cortex surface






23. Measures oxygen flow in different brain areas - used most in cognitive psych to measure activity in different brain regions during certain tasks






24. Of Hindbrain - aka medulla; Mainly controls for reflexes - but also controls sleep - attention - movement






25. Gray matter - white matter






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






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






28. Bumps on the brainstem - controls auditory reflexes






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






30. Provide myelin in central nervous system






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






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






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






34. Chemicals that stimulate nearby cells






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






36. Comprise two classes of neurotransmitters - indolamines and catecholamines






37. (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






38. Bundles of axon - Nerve fiber






39. 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






40. 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






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






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






43. Inner core of spine - cell bodies and dendrites






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






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






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






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






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






49. Made of thalamus and hypothalamus






50. Between myelin sheath - help send impulse down axon
