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






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






3. Of cerebral cortex - responsible for somatosensory system






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






5. PNS fibers that run towards CNS






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






7. 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






8. Chemicals that stimulate nearby cells






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






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






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






12. An amino acid - most abundant excitatory neurotransmitter.






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






14. Of cerebral cortex - responsible for vision






15. Fissures seen on cortex surface






16. Of Hindbrain - aka medulla; Mainly controls for reflexes - but also controls sleep - attention - movement






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






18. Bundles of axon - Nerve fiber






19. PNS - interacts with internal environment - - Responsible for the 'fight or flight' response - - It controls the involuntary functions including movement of smooth muscles - digestion - blood circulation - breathing






20. Bumps seen on cortex surface






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






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






23. Incredible rage easily provoked when cerebral cortex is removed






24. Connections between brain and spine






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






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






27. PNS - interacts with external environment by controlling voluntary movements of striated muscles






28. End of a neuron (terminal buttons)






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






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






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






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






34. 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






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






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






37. Of diencephalon - channels sensory information to cerebral cortex






38. Bumps on the brainstem - controls visual reflexes






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






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






42. 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






43. Comprise two classes of neurotransmitters - indolamines and catecholamines






44. Holds neurotransmitters






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






46. Low-amplitude and fast -frequency alpha waves






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






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






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






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