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






2. 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






3. Stage 1 & 2 non-REM sleep (with sleep spindles) - lower-amplitude and slower frequency waves






4. 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






5. Inactivated state of a neuron






6. Fissures seen on cortex surface






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






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






9. 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)

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






11. An amino acid - most abundant excitatory neurotransmitter.






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






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






14. Where soma and axon connect






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






16. Contain synaptic vessels that hold neurotransmitters






17. Organizational and activational






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






19. Time after a neuron fires which it cannot respond to stimulation






20. Of pituitary - activates thyroid






21. 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






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






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






24. Bumps seen on cortex surface






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






26. Made up of brain and spinal cord






27. Connections between brain and spine






28. Of cerebral cortex - responsible for vision






29. 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






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






31. Bumps on the brainstem - controls visual reflexes






32. (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






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






34. Made of thalamus and hypothalamus






35. Divided into diencephalon and telencephalon






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






37. 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






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






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






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






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






42. 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






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






44. Of cerebral cortex - responsible for somatosensory system






45. REM-sleep - low-amplitude and fast-frequency waves that characterize waking states






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






47. Provide myelin in central nervous system






48. PNS fibers that run towards CNS






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






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
