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. Maintains balance/posture and coordinates body movements






2. A drug that facilitates the effects of a particular neurotransmitter on the postsynaptic cell






3. A large network of neural tissue located in the central region of the brain stem - from the medulla to the diencephalon






4. Instead of one continuum for sex (masculine-feminine) - her work in the presence of both masculine and feminine features/development suggests these are actually two separate continuums (defeminized-feminized and unmasculinized-masculinized)

5. The female reproductive cycle of most primates - including humans; recognized by growth of the lining of the uterus - ovulation - development of a corpus luteum - and (if pregnancy does not occur) menstration






6. Short bursts of waves 12-14 Hz that occur 2-5 times a minute during stages 1-4 of sleep; most characteristic of sleep Stage II; some believe sleep spindles are involved in keeping one asleep (decline in older people)






7. Combines input from diverse brain regions; receives sensory information/sends motor impulses






8. Symptom of narcolepsy - irresistible urge to






9. Lens changes initiated by the ciliary muscles to change the shape of the lens in order to focus image on the retina






10. Part of limbic system; protrusion of the bottom of the brain at the posterior end of the hypothalamus - contains some hypothalamic nuclei






11. Strip of limbic cortex lying along the lateral walls of the groove separating the cerebral hemispheres - just above the corpus callosum






12. Auditory receptor cells in the cochlea that turn sound vibrations -> neural impulses






13. Comprised of the hypothalamus - pituitary gland - thyroid gland - parathyroid - the adrenal cortex - the adrenal medulla - the pancreas - the ovaries/testes - pineal gland.






14. Binding of drug to receptor site that doesn'T interfere with the principal ligand






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






16. Self-dissolving






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






18. 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)






19. Activates one of 5 types of receptors in the CNS - cognition - motor activity - reward - muscle tone - sleep - mood - attention - learning -higher level effects of dopamine = D2






20. Found in the hypothalamus - function to maintain the water balance in the body






21. Research indicates that the expressing of negative emotions is associated with increased immune function; inhibiting negative emotions with decreasing immune function






22. Occur in amacrine - bipolar and horizontal cells; govern/encompass the opponent-process level of color vision






23. Projects to ventral tegmental area






24. Include indolamines (serotonin) and catecholamines (dopamine - norepinephrine and epinephrine)






25. 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






26. Irregular electrical activity of 13-30 Hz - state of arousal - attentive






27. Is characteristic of indirect antagonist drugs






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






29. Result in either tolerance (and possible withdrawal symptoms) or sensitization (increase effectiveness of the drug)






30. Optic Nerve - sight






31. Governs eating/drinking (lateral and ventromedial hypothalami) and sexual activity (anterior portion






32. learning and memory -neurotransmitter released at the neuromuscular junction of skeletal muscle axons to excite the muscle to contract






33. A BEHAVIOR; insistent urge of sleepiness forces us to seek sleep/a bad






34. The visual image of the world on the retina






35. Pleasure center of the brain; discovered by Olds & Milner






36. First described by Descartes - a combination of antagonistic muscle movements (e.g. those involved in walking)






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






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






39. Also known as ABLATION - is any surgically induced brain lesion






40. Suggests that dreams are nothing more than the product of random electrical impulses (Hobson & McCarley)






41. 'Roof'






42. Has a major role in metabolism - stimulation/maintenance - produces the hormones thyroxin and calcitonin






43. Sudden - sharp waveforms found only in Stage II of sleep; spontaneously occur about one per minute but also to unexpected noises






44. Choroid Plexus > Ventricle 1 & 2 > Foramen of Monro > Ventricle 3 > Aqueduct of Sylvius > Ventricle 4 > Foramen of Magendie lateral aperture) > Foramina of Luschka (lateral aperture) - subarachnoid space (outside of brain) and spinal cord > re-absorp






45. Functions as both a hormone and a neurotransmitter in the brain






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






47. Is a receptor blocker; binds with a receptor but does not activate it - actually prevents the natural ligand from binding with the receptor






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






49. Attaches to the binding site on a receptor and interferes with the receptor'S action - but NOT by interfering with the principal ligand'S binding site (noncompetitive binding)






50. Consummatory stimulus
