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






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






3. Fissures seen on cortex surface






4. Organizational and activational






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






6. Provide myelin in peripheral nervous system






7. 16 hours of sleep a day - 6 hours






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






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






10. Chemicals that stimulate nearby cells






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






12. 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






13. Jumping from one node of Ranvier to the next due to insulation by myelin sheath






14. 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






15. An amino acid - most abundant excitatory neurotransmitter.






16. comprises 50% of total sleep at birth - decreases to 25% - 20% sleep time spent in this type of sleep - Interspersed with non-REM every 30-40min - where dreams are experience - characterized by neural desynchrony - also known as paradoxical sleep -->






17. Bumps on the brainstem - controls visual reflexes






18. 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






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






20. Bumps on the brainstem - controls auditory reflexes






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






22. Of cerebral cortex - responsible for vision






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






24. PNS fibers that run away from CNS (to cause effect the brain wants)






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






26. Incredible rage easily provoked when cerebral cortex is removed






27. Dysfunction in certain cortical association area - difficulty processing sensory information






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






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






30. Midbrain; contains tectum and tegmentum






31. Comprise two classes of neurotransmitters - indolamines and catecholamines






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






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






34. Low-amplitude and fast -frequency alpha waves






35. Of mesencephalon - vision and hearing






36. Made of thalamus and hypothalamus






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






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






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






40. 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


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






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






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






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






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






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






47. 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






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






49. Pathway that runs to and from CNS






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