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. Pathway that runs to and from CNS






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






3. Fissures seen on cortex surface






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






5. Bumps on the brainstem - controls auditory reflexes






6. Where soma and axon connect






7. Gray matter - white matter






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






9. Connections between brain and spine






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






11. Low-amplitude and fast -frequency alpha waves






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






13. Divided into diencephalon and telencephalon






14. Made of thalamus and hypothalamus






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






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






17. Of pituitary - activates thyroid






18. 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






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






20. Contain synaptic vessels that hold neurotransmitters






21. Bumps seen on cortex surface






22. Bumps on the brainstem - controls visual reflexes






23. PNS fibers that run towards CNS






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






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






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






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






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






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






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






31. (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






32. 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






33. Base in hindbrain - rest in midbrain; oldest brain area; Controls alertness - thirst - sleep - involuntary muscles (i.e. heart)






34. 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 -->






35. Of cerebral cortex - responsible for vision






36. An amino acid - most abundant inhibitory neurotransmitter






37. 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






38. Of diencephalon - channels sensory information to cerebral cortex






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






40. End of a neuron (terminal buttons)






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






42. Incredible rage easily provoked when cerebral cortex is removed






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






44. Bundles of axon - Nerve fiber






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






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






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






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






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






50. Beginning of neuron (dendrites)
