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. Made up of sympathetic nervous system and parasympathetic nervous system






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






3. Connections between brain and spine






4. Inactivated state of a neuron






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






6. Bumps on the brainstem - controls visual reflexes






7. Provide myelin in central nervous system






8. Consists of myelencephalon - metencephalon - and reticular formation






9. 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






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






11. Fissures seen on cortex surface






12. Covers whole neuron - selective permeability - sometimes lets ions (positive charge) through






13. Or just synapse - the space between 2 neurons where they communication






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






15. Present in fast-acting - directed synapses






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






17. Bumps on the brainstem - controls auditory reflexes






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






19. Low-amplitude and fast -frequency alpha waves






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






21. 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)

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






23. PNS fibers that run towards CNS






24. 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 -->






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






26. 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






27. End of a neuron (terminal buttons)






28. 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






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






30. Of pituitary - activates thyroid






31. 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






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






33. Provide myelin in peripheral nervous system






34. Contain synaptic vessels that hold neurotransmitters






35. Inner core of spine - cell bodies and dendrites






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






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






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






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






40. Holds neurotransmitters






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






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






43. Made up of brain and spinal cord






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






45. Bumps seen on cortex surface






46. Time after absolute refractory period - neuron can fire but needs a much stronger stimulus






47. (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






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






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






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