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






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






3. Comprise two classes of neurotransmitters - indolamines and catecholamines






4. 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






5. 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






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






7. 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






8. Present in fast-acting - directed synapses






9. Inactivated state of a neuron






10. Low-amplitude and fast -frequency alpha waves






11. 16 hours of sleep a day - 6 hours






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






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






14. Contain synaptic vessels that hold neurotransmitters






15. Gray matter - white matter






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






17. Of mesencephalon - rest of reticular formation; Also involved in the sensorimotor system - analgesic effect of opiates






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






19. Where soma and axon connect






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






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






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






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






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






26. Chemicals that stimulate nearby cells






27. Associated with changes in hormone levels throughout the month - estradiol - progesterone - luteinizing hormone - follicle stimulating hormone






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






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






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






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






32. 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






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






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






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






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






37. Bumps seen on cortex surface






38. An amino acid - most abundant inhibitory neurotransmitter






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






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






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






42. Bumps on the brainstem - controls auditory reflexes






43. Divided into diencephalon and telencephalon






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






45. Made up of brain and spinal cord






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






47. Connections between brain and spine






48. Consists of myelencephalon - metencephalon - and reticular formation






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






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