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






2. 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






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






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






5. Bundles of axon - Nerve fiber






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






7. Bumps seen on cortex surface






8. Provide myelin in central nervous system






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






10. Dysfunction in certain cortical association area - language disorder from damage to Wernicke'S area - in left temporal lobe; can speak but doesn'T understand how to correctly choose words (fluent but nonsensical)

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






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






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






14. 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






15. Incredible rage easily provoked when cerebral cortex is removed






16. 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






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






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






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






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






21. An amino acid - most abundant excitatory neurotransmitter.






22. Gray matter - white matter






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






24. 16 hours of sleep a day - 6 hours






25. Low-amplitude and fast -frequency alpha waves






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






27. Contain synaptic vessels that hold neurotransmitters






28. Inactivated state of a neuron






29. Of cerebral cortex - responsible for hearing - also Wernicke'S area (related to speech)






30. 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






31. PNS fibers that run towards CNS






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






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






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






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






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






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






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






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






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






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






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






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






44. Of pituitary - activates thyroid






45. Of cerebral cortex - responsible for somatosensory system






46. Chemicals that stimulate nearby cells






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






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






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






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