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






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






3. Where soma and axon connect






4. Comprise two classes of neurotransmitters - indolamines and catecholamines






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






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






7. The process after a neurotransmitter has done its job - it is reabsorbed by the presynaptic cell






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






9. Low-amplitude and fast -frequency alpha waves






10. Of mesencephalon - vision and hearing






11. Gray matter - white matter






12. Fatty - insulating sheath on some axons for faster conduction of axon impulses






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






14. Bumps on the brainstem - controls visual reflexes






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






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






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






18. Connections between brain and spine






19. Linked to pleasure and analgesia; can be endogenous (opioid peptides) or exogenous (morphine or heroin) - Exogenous endorphine are highly addictive






20. Inner core of spine - cell bodies and dendrites






21. Chemicals that stimulate nearby cells






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






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






24. Of cerebral cortex - responsible for somatosensory system






25. PNS fibers that run towards CNS






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






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






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






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






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






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






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






33. Pathway that runs to and from CNS






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






35. 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






36. Bundles of axon - Nerve fiber






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






38. Bumps on the brainstem - controls auditory reflexes






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






40. 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






41. 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






42. Bumps seen on cortex surface






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






44. Made up of brain and spinal cord






45. An amino acid - most abundant inhibitory neurotransmitter






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






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






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






49. 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)

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