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. Divided into diencephalon and telencephalon






2. Bumps seen on cortex surface






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






4. Where soma and axon connect






5. Fissures seen on cortex surface






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






7. Low-amplitude and fast -frequency alpha waves






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






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






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






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






12. Overeating with no satiation of hunger; leads to obesity; damage to ventromedial region of hypothalamus






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






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






15. Gray matter - white matter






16. Of cerebral cortex - responsible for somatosensory system






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






18. Takes about half an hour; (0) prelude to sleep - neural synchrony; alpha waves; person is relaxed and drowsy - closes eye; (1) Eyes begin to roll. alpha waves give way to irregular theta waves; loses responsiveness to stimuli - experiences fleeting t






19. Present in fast-acting - directed synapses






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






21. 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






22. Beginning of neuron (dendrites)






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






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






25. Stage 1 & 2 non-REM sleep (with sleep spindles) - lower-amplitude and slower frequency waves






26. 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






27. An amino acid - most abundant inhibitory neurotransmitter






28. Inner core of spine - cell bodies and dendrites






29. Made of thalamus and hypothalamus






30. Holds neurotransmitters






31. Bundles of axon - Nerve fiber






32. 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






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






34. Provide myelin in peripheral nervous system






35. Provide myelin in central nervous system






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






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






38. Of mesencephalon - vision and hearing






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






40. Incredible rage easily provoked when cerebral cortex is removed






41. An amino acid - most abundant excitatory neurotransmitter.






42. 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






43. Of pituitary - stress hormone - increases androgen and cortisol production






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






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






46. Dysfunction in certain cortical association area - language disorder from damage to Wernicke'S area - in left temporal lobe; can speak but doesn'T understand how to correctly choose words (fluent but nonsensical)

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


47. Chemicals that stimulate nearby cells






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






49. Used to implant electrodes into animals' brains in experiments






50. Bumps on the brainstem - controls auditory reflexes
