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. Dysfunction in certain cortical association area - inability to read






2. 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 -->






3. Controlled by hypothalamus - regulation of hormones in the body - The 'master gland' of the endocrine/hormone system






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






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






6. Made up of brain and spinal cord






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






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






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






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






11. Between myelin sheath - help send impulse down axon






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






13. Holds neurotransmitters






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






15. Made of thalamus and hypothalamus






16. Low-amplitude and fast -frequency alpha waves






17. Of cerebral cortex - responsible for vision






18. Pathway that runs to and from CNS






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






20. Of cerebral cortex - responsible for somatosensory system






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






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






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






24. 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






25. 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






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






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






28. Inactivated state of a neuron






29. Of mesencephalon - vision and hearing






30. 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)

31. Contain synaptic vessels that hold neurotransmitters






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






33. Comprise two classes of neurotransmitters - indolamines and catecholamines






34. Where soma and axon connect






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






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






37. Connections between brain and spine






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






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






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






41. Provide myelin in peripheral nervous system






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






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






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






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






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






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






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






49. End of a neuron (terminal buttons)






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