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






2. Inner core of spine - cell bodies and dendrites






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






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






5. Of mesencephalon - vision and hearing






6. 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






7. 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






8. Made of thalamus and hypothalamus






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






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






11. An amino acid - most abundant excitatory neurotransmitter.






12. Present in fast-acting - directed synapses






13. Time after absolute refractory period - neuron can fire but needs a much stronger stimulus






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






15. Inactivated state of a neuron






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






17. Where soma and axon connect






18. Consists of myelencephalon - metencephalon - and reticular formation






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






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






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






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






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






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






25. An amino acid - most abundant inhibitory neurotransmitter






26. Control large voluntary muscle movements - Their degeneration is related to motor dysfunction in Parkinson'S and Huntington'S






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






28. Used to implant electrodes into animals' brains in experiments






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






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






31. Of diencephalon - channels sensory information to cerebral cortex






32. 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






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






34. Of cerebral cortex - responsible for somatosensory system






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






36. Provide myelin in central nervous system






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






38. Incredible rage easily provoked when cerebral cortex is removed






39. Bundles of axon - Nerve fiber






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






41. (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






42. End of a neuron (terminal buttons)






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






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






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






46. Bumps seen on cortex surface






47. Beginning of neuron (dendrites)






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






49. Areas on cortex that correspond to certain functions; - the larger the area - the more sensitive and highly accessed the function - Damage to a particular area would result in certain dysfunction






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