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






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






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






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






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






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






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






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






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






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






11. Organizational and activational






12. Dysfunction in certain cortical association area - inability to read






13. Contain synaptic vessels that hold neurotransmitters






14. 16 hours of sleep a day - 6 hours






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






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






17. Divided into diencephalon and telencephalon






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






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






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






21. Inner core of spine - cell bodies and dendrites






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






23. Low-amplitude and fast -frequency alpha waves






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






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






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






27. Bumps seen on cortex surface






28. Comprise two classes of neurotransmitters - indolamines and catecholamines






29. An amino acid - most abundant excitatory neurotransmitter.






30. Connections between brain and spine






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






32. 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)

Warning: Invalid argument supplied for foreach() in /var/www/html/basicversity.com/show_quiz.php on line 183


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






34. Associated with changes in hormone levels throughout the month - estradiol - progesterone - luteinizing hormone - follicle stimulating hormone






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






36. Inactivated state of a neuron






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






38. Where soma and axon connect






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






40. Of hindbrain - has pons(connects brain parts to spine) and cerebellum(controls muscle coordination - balance - posture)






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






42. 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






43. 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






44. Bundles of axon - Nerve fiber






45. Consists of myelencephalon - metencephalon - and reticular formation






46. Bumps on the brainstem - controls visual reflexes






47. 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 -->






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






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






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