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






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






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






4. Pathway that runs to and from CNS






5. Gray matter - white matter






6. Bundles of axon - Nerve fiber






7. Provide myelin in peripheral nervous system






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






9. Organizational and activational






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






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






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






13. Of pituitary - activates thyroid






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






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






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






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






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






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






20. Consists of myelencephalon - metencephalon - and reticular formation






21. 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






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






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






24. 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






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






26. 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






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






28. PNS fibers that run towards CNS






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






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






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






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






33. Of diencephalon - channels sensory information to cerebral cortex






34. 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)

Warning: Invalid argument supplied for foreach() in /var/www/html/basicversity.com/show_quiz.php on line 183


35. Midbrain; contains tectum and tegmentum






36. Include dopamine - lack of dopamine linked with Parkinson'S - excess dopamine is linked with schizophrenia - dopamine is also involved in feelings of reward and therefore addiction






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






38. Inactivated state of a neuron






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






40. Inner core of spine - cell bodies and dendrites






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






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






43. Divided into diencephalon and telencephalon






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






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






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






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






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






49. Of cerebral cortex - responsible for somatosensory system






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