Gre Psychology: Experimental/natural Science Biology

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. The female reproductive cycle of mammals other than primates






2. Increases heartrate - dilates/constricts blood vessels - increases blood sugar - produces hormones epinephrine and norepinephrine






3. One of the primary noradrenergic nuclei whose ascending axons project to frontal cortex - thalamus - hypothalamus - limbic system






4. Affect multiple receptors; highly preferential to which type of receptor they affect






5. 1. ventral tegmentum to mesolimbic forebrain (cognition - reward systems - emotional behavior) 2. substantia nigra to caudate nucleus putamen (movement and sensory stimulation) 3. hypothalamus to pituitary gland (neuronal/hormonal control)






6. A behavior that has different forms or occurs with different probabilities or under different circumstances in males than females






7. Reduces anxiety - released with NE in amygdala - hippocampus - basal ganglia - periaqueductal gray region - locus coeruleus and PFS; NPY is diminished in persons with PTSD/CPTSD and those exposed to chronic stress






8. The earlier onset of puberty seen in female animals that are housed with males caused by a pheromone in the male'S urine and first observed in mice






9. A chemical released by one animal that affects the behavior or physiology of another animal; usually smelled or tasted






10. In the posterior frontal lobe - contains the somatosensory cortex (touch - pressure - temperature - pain)






11. Vision: protrusions on top of the midbrain; part of visual system






12. Accessory Nerve - moves the head






13. Optic Nerve - sight






14. Receive incoming sensory information or send out motor impulse commands






15. Controls circadian rhythms - produces melatonin (daylight signals go to the eyes to the hypothalamus to the pineal gland)






16. EEG desynchrony (rapid -irregular waves) - lack of muscle tonus - rapid eye movements - penile erection/vaginal secretion - dreams; EEG synchrony (slow waves) - moderate muscle tonus - slow/absent eye movements - lack of genital activity






17. Occurs at the onset of puberty; a hypothalamic hormone that stimulates the pituitary gland to secrete gonadotropin






18. 'covering'






19. Means 'Savory' in Japanese and is a taste receptor found on the tongue; activated by glutamate present in meats - cheese and other protein heavy foods






20. Audition: protrusions on top of midbrain; part of auditory system






21. Is found between the arachnoid mater and Pia mater; this is where CSF cushions (and bathes) the brain - giving it the floating quality (and keeping it moist/circulating)






22. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in prefrontal cortex






23. In the CNS - is an amino acid that stabilizes neural activity






24. ...






25. Vestibulocochlear Nerve - hearing and balance






26. SCN = controls circadian rhythms - located directly above the optic chasm in the anterior portion of the hypothalamus - receives input from the eyes which is why light exposure affects our sleep-wake cycles






27. Opening in the iris; dilates and contracts allowing different levels of light in






28. Associated with defensive and aggressive behavior; lesions produce docility and hypersexual states (Kluver & Bucy)






29. Forebrain -band of nerve fibers connecting the two cerebral hemispheres






30. Contains receptors to detect when the body needs food or fluids; the hunger center; lesions lead to aphagia






31. AKA the striate cortex - located at the back of the brain - and contains the visual cortex






32. Abducens Nerve - moves eye






33. Oculomotor Nerve - moves eye pupil






34. Hypothalamic-pituitary-adrenal axis -controls stress response






35. An anterograde amnesia in which one cannot form episodic memories BUT in experiments - patients that cannot identify previously heard melodies do show a preference for them -> explicit memory function has a different neurological basis than implicit


36. Those biological considerations which are IMMEDIATE;Behavioral/Cognitive Neuroscience (i.e. how the nervous and endocrine systems influence behaviors/thoughts)






37. States that performance is worst at extremely low or extremely high levels of arousal and optimally at an intermediate level






38. Maintains balance/posture and coordinates body movements






39. Convoluted of hills (gyri) and valleys (sulci) divided into two hemispheres (left and right) which are further divided into four lobes (occipital - parietal - temporal and frontal)






40. The viscous substance between cornea and lens






41. Absolute; relative






42. Ventral part of midbrain - includes periaqueductal gray matter - reticular formation - red nucleus - and substantia nigra






43. The Lee-Boot effect - Whitten effect - Vandenbergh effect - and the Bruce effect; all mediated by the VNO






44. Hypoglossal Nerve - moves the tongue






45. In the tegmentum (ventral part of midbrain); its neurons connect to caudate nucleus + putamen (in basal ganglia)






46. Junction of the sagittal and coronal sutures of the skull; often used as a reference point for stereotaxic brain surgery






47. 1. Stage I (non-REM sleep) 2. Stage II (non-REM sleep 3. Stage III (non-REM sleep - slow-wave sleep) 4. Stage IV (non-REM sleep - slow-wave sleep) 5. Rapid Eye Movement Sleep (REM sleep) ~takes about 90 minutes for one full sleep cycle






48. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in the nucleus accumbens - amygdala and hippocampus






49. Damage to this are causes clumsiness and loss of balance






50. Holds the lens in place
