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. Low-amplitude and fast -frequency alpha waves






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






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






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






5. Present in fast-acting - directed synapses






6. 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 -->






7. Of telencephalon - involves in memory- transfer STM into LTM - - new neurons can form in adult mammalian brain






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






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






10. Dysfunction in certain cortical association area - inability to organize movement






11. 16 hours of sleep a day - 6 hours






12. Pathway that runs to and from CNS






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






14. 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






15. PNS fibers that run towards CNS






16. Of cerebral cortex - responsible for vision






17. Holds neurotransmitters






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






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






20. Made up of brain and spinal cord






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






22. Of pituitary - stress hormone - increases androgen and cortisol production






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






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






25. Incredible rage easily provoked when cerebral cortex is removed






26. 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






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






28. Beginning of neuron (dendrites)






29. 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)

30. An amino acid - most abundant inhibitory neurotransmitter






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






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






33. Inactivated state of a neuron






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






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






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






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






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






39. Of diencephalon - channels sensory information to cerebral cortex






40. A type of cell that help support neurons; oligodendrocytes and Schwann cells






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






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






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






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






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






46. Released at neuromuscular junction to cause contraction of skeletal muscles - also involved in parasympathetic nervous system






47. Of pituitary - activates thyroid






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






49. 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






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