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






2. 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






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






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






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






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






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






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






9. Of cerebral cortex - responsible for vision






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






11. Contain synaptic vessels that hold neurotransmitters






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






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






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






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






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






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






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






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






20. Provide myelin in peripheral nervous system






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






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






23. Made up of brain and spinal cord






24. Comprise two classes of neurotransmitters - indolamines and catecholamines






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






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






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






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






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






30. 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






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






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






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






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






35. Chambers filled with cerebrospinal fluid that insulate brain from shock






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






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






38. Protects the brain by making it difficult for toxic substances to pass from the blood into the brain - since blood vessel cells in the brain are tightly packed






39. 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






40. Gray matter - white matter






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






42. Fissures seen on cortex surface






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






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






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






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






47. Made of thalamus and hypothalamus






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






49. Of pituitary - activates thyroid






50. Holds neurotransmitters
