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






2. An amino acid - most abundant inhibitory neurotransmitter






3. Dysfunction in certain cortical association area - difficulty processing sensory information






4. 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






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






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






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






8. Holds neurotransmitters






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






10. Incredible rage easily provoked when cerebral cortex is removed






11. Organizational and activational






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






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






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






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






16. Dysfunction in certain cortical association area - inability to write






17. Divided into diencephalon and telencephalon






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






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






20. End of a neuron (terminal buttons)






21. 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






22. Of cerebral cortex - responsible for somatosensory system






23. Of cerebral cortex - responsible for vision






24. Inactivated state of a neuron






25. Provide myelin in peripheral nervous system






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






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






28. comprises 50% of total sleep at birth - decreases to 25% - 20% sleep time spent in this type of sleep - Interspersed with non-REM every 30-40min - where dreams are experience - characterized by neural desynchrony - also known as paradoxical sleep -->






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






30. Where soma and axon connect






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






32. An amino acid - most abundant excitatory neurotransmitter.






33. Bumps seen on cortex surface






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






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






36. Between myelin sheath - help send impulse down axon






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






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






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






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






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






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






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






44. Made up of brain and spinal cord






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






46. Fissures seen on cortex surface






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






48. Midbrain; contains tectum and tegmentum






49. Inner core of spine - cell bodies and dendrites






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