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. Low-amplitude and fast -frequency alpha waves






2. Pathway that runs to and from CNS






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






4. ANS - recuperation after arousal (decrease HR - BP - respiration)






5. 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






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






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






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






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






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






11. Provide myelin in central nervous system






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






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






14. 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






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






16. Bundles of axon - Nerve fiber






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






18. Inner core of spine - cell bodies and dendrites






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






20. Chemicals that stimulate nearby cells






21. Organizational and activational






22. Contain synaptic vessels that hold neurotransmitters






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






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






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






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






27. Bumps seen on cortex surface






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






29. Of cerebral cortex - responsible for somatosensory system






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






31. Bumps on the brainstem - controls visual reflexes






32. Fatty - insulating sheath on some axons for faster conduction of axon impulses






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






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






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






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






37. 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






38. Made up of brain and spinal cord






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






40. Midbrain; contains tectum and tegmentum






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






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






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






44. 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






45. 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


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






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






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






49. Of pituitary - activates thyroid






50. Beginning of neuron (dendrites)
