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






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






3. Bumps on the brainstem - controls visual reflexes






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






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






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






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






8. Connections between brain and spine






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






10. Consists of myelencephalon - metencephalon - and reticular formation






11. Organizational and activational






12. Pathway that runs to and from CNS






13. Dysfunction in certain cortical association area - inability to organize movement






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






15. (1) resting potential - neuron negatively charged - cell membrane does not let ions in; (2) presynaptic cell releases neurotransmitters from terminal buttons; (3) postsynaptic receptors in postsynaptic cells detects neurotransmitter and open ion chan






16. Of cerebral cortex - responsible for somatosensory system






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






18. Beginning of neuron (dendrites)






19. Of mesencephalon - vision and hearing






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






21. 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






22. Inactivated state of a neuron






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






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






25. 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






26. Fast frequency bursts of brain activity - inhibits processing to keep tranquil state






27. Bundles of axon - Nerve fiber






28. Bumps seen on cortex surface






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






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






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






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






33. 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






34. Bumps on the brainstem - controls auditory reflexes






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






36. Occur during specific periods in development - permanent or long-lasting effects; - presence of H-Y antigen in development causes fetus to develop into a male - absence to female; - androgens in males and estrogen in females causes secondary sex cha






37. Controlled by hypothalamus - regulation of hormones in the body - The 'master gland' of the endocrine/hormone system






38. Present in fast-acting - directed synapses






39. Low-amplitude and fast -frequency alpha waves






40. Inner core of spine - cell bodies and dendrites






41. Provide myelin in central nervous system






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






43. 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






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






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






46. Of telencephalon - structures around the brainstem involved in 4Fs (fleeing - feeding - fighting - and fornicating)






47. 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


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






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






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