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. Inactivated state of a neuron






2. Takes about half an hour; (0) prelude to sleep - neural synchrony; alpha waves; person is relaxed and drowsy - closes eye; (1) Eyes begin to roll. alpha waves give way to irregular theta waves; loses responsiveness to stimuli - experiences fleeting t






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






4. Gray matter - white matter






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






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






7. Inner core of spine - cell bodies and dendrites






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






9. Where soma and axon connect






10. Of mesencephalon - vision and hearing






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






12. 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






13. 16 hours of sleep a day - 6 hours






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






15. 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






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






17. Connections between brain and spine






18. Divided into diencephalon and telencephalon






19. Measures oxygen flow in different brain areas - used most in cognitive psych to measure activity in different brain regions during certain tasks






20. Provide myelin in peripheral nervous system






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






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






23. End of a neuron (terminal buttons)






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






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






26. 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






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






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






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






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






31. Made of thalamus and hypothalamus






32. 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






33. Released from the pituitary and facilitates birth and breast feeding - also involved in pair bonding (mother to child or romantic partners) -






34. Beginning of neuron (dendrites)






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






36. Holds neurotransmitters






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






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






39. Of cerebral cortex - responsible for vision






40. Of pituitary - activates thyroid






41. Present in fast-acting - directed synapses






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






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






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






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






46. 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 -->






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






48. Between myelin sheath - help send impulse down axon






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






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