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. 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






2. An amino acid - most abundant excitatory neurotransmitter.






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






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






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






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






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






8. Of pituitary - activates thyroid






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






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






11. Of cerebral cortex - responsible for somatosensory system






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






13. Areas on cortex that correspond to certain functions; - the larger the area - the more sensitive and highly accessed the function - Damage to a particular area would result in certain dysfunction






14. Of mesencephalon - vision and hearing






15. Bumps seen on cortex surface






16. Midbrain; contains tectum and tegmentum






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






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






19. 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






20. Consists of myelencephalon - metencephalon - and reticular formation






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






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






23. Of cerebral cortex - responsible for vision






24. Low-amplitude and fast -frequency alpha waves






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






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






27. Inactivated state of a neuron






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






29. Bumps on the brainstem - controls auditory reflexes






30. Contain synaptic vessels that hold neurotransmitters






31. Provide myelin in central nervous system






32. Holds neurotransmitters






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






34. Provide myelin in peripheral nervous system






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






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






37. 16 hours of sleep a day - 6 hours






38. Made of thalamus and hypothalamus






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






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






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






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






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






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






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






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






47. Between myelin sheath - help send impulse down axon






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






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






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