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. Comprise two classes of neurotransmitters - indolamines and catecholamines






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






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






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






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






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






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






8. Holds neurotransmitters






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






10. 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)

11. An amino acid - most abundant inhibitory neurotransmitter






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






13. Include serotonin - lack of serotonin is linked with depression






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






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






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






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






18. 4-6 complete ones - each about 90 minutes - early in the night most time in stage 3 and 4 - 2 and REM sleep predominate later






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






20. Contain synaptic vessels that hold neurotransmitters






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






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






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






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






25. Bumps on the brainstem - controls auditory reflexes






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






27. An amino acid - most abundant excitatory neurotransmitter.






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






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






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






31. Bumps on the brainstem - controls visual reflexes






32. Made of thalamus and hypothalamus






33. 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






34. 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






35. End of a neuron (terminal buttons)






36. Gray matter - white matter






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






38. Control large voluntary muscle movements - Their degeneration is related to motor dysfunction in Parkinson'S and Huntington'S






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






40. 16 hours of sleep a day - 6 hours






41. Between myelin sheath - help send impulse down axon






42. 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






43. Of diencephalon - channels sensory information to cerebral cortex






44. Low-amplitude and fast -frequency alpha waves






45. Inner core of spine - cell bodies and dendrites






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






47. Of cerebral cortex - responsible for somatosensory system






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






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






50. Divided into diencephalon and telencephalon
