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. Of cerebral cortex - responsible for vision






2. Beginning of neuron (dendrites)






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






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






5. Incredible rage easily provoked when cerebral cortex is removed






6. (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






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






8. Consists of myelencephalon - metencephalon - and reticular formation






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






10. Of pituitary - activates thyroid






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






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






13. Chemicals that stimulate nearby cells






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






15. 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






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






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






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






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






20. Dysfunction in certain cortical association area - inability to read






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






22. Consists of limbic system - hippocampus - amygdala - cingulate gyrus






23. 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






24. Midbrain; contains tectum and tegmentum






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






26. End of a neuron (terminal buttons)






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






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






29. Low-amplitude and fast -frequency alpha waves






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






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






33. Bumps on the brainstem - controls visual reflexes






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






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






36. Presence during development causes a fetus to develop into a male (absence cause the fetus to develop into a female)






37. Increase effects of a neurotransmitter (e.g. selective serotonin reuptake inhibitors [for depression] increase serotonin activity)






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






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






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






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






42. Inactivated state of a neuron






43. Where soma and axon connect






44. Bumps on the brainstem - controls auditory reflexes






45. Between myelin sheath - help send impulse down axon






46. Inner core of spine - cell bodies and dendrites






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






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






49. 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






50. Divided into diencephalon and telencephalon
