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. Holds neurotransmitters






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






3. Fissures seen on cortex surface






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






5. 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 -->






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






7. 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






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






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






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






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






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






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






14. PNS fibers that run towards CNS






15. Bumps seen on cortex surface






16. An amino acid - most abundant excitatory neurotransmitter.






17. Stage 3 (less sleep spindles) & 4 non-REM sleep - high-amplitude and low-frequency - deepest level of sleep






18. (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






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






20. Inactivated state of a neuron






21. Contain synaptic vessels that hold neurotransmitters






22. Consists of myelencephalon - metencephalon - and reticular formation






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






24. Of pituitary - activates thyroid






25. Made up of brain and spinal cord






26. Stage 0 & 1 non-REM sleep - low-amplitude and fast-frequency waves






27. Provide myelin in peripheral nervous system






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






29. Gray matter - white matter






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






31. Incredible rage easily provoked when cerebral cortex is removed






32. Bumps on the brainstem - controls visual reflexes






33. Connections between brain and spine






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






35. Between myelin sheath - help send impulse down axon






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






37. 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)

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


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






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






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






41. 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


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






44. 16 hours of sleep a day - 6 hours






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






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






47. Present in fast-acting - directed synapses






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






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






50. The basic unit of the nervous system - Consist of: Dentrites - cell body (soma) - axon hillock - axon - myelin sheath - nodes of Ranvier - Terminal buttons - cell membrane - synapse - glial cells
