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. Consists of myelencephalon - metencephalon - and reticular formation






2. 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






3. 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)


4. Low-amplitude and fast -frequency alpha waves






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






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






7. Inner core of spine - cell bodies and dendrites






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






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






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






11. Where soma and axon connect






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






13. An amino acid - most abundant inhibitory neurotransmitter






14. 16 hours of sleep a day - 6 hours






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






16. Pathway that runs to and from CNS






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






18. Present in fast-acting - directed synapses






19. Bumps on the brainstem - controls auditory reflexes






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






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






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






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






24. The basic unit of the nervous system - Consist of: Dentrites - cell body (soma) - axon hillock - axon - myelin sheath - nodes of Ranvier - Terminal buttons - cell membrane - synapse - glial cells






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






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






27. Made up of brain and spinal cord






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






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






30. Increase effects of a neurotransmitter (e.g. selective serotonin reuptake inhibitors [for depression] increase serotonin activity)






31. Bumps seen on cortex surface






32. Divided into diencephalon and telencephalon






33. Bundles of axon - Nerve fiber






34. Transmits impulses of neuron - bundles of these are nerve fibers (white matter); the wider nerve fiber - the faster its conduction






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






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






37. Chambers filled with cerebrospinal fluid that insulate brain from shock






38. 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






39. Of mesencephalon - vision and hearing






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






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






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






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






44. Between myelin sheath - help send impulse down axon






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






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






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






48. 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






49. Beginning of neuron (dendrites)






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