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 increase in REM sleep seen after a period of REM sleep deprivation






2. Measure changes in the electrical resistance of the skin (sweat gland activity)






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






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






5. Decreases with age up until age 30 - then begins to increase *(counter intuitive)*






6. Symptom of narcolepsy - paralysis occurring just before a person falls alseep






7. The synchronization of the menstrual or estrous cycles of a group of females - which occurs only in the presence of a pheromone in a male'S urine






8. Portion of a sensory field to which a cell responds






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






10. Similarity of alleles for a trait in an organism (i.e. heterozygous or homozygous)






11. Most brain communications are with the opposite side of the body






12. Somewhat excitatory - also involved in synaptic plasticity - learning and short-term memory






13. Absolute; relative






14. Affect sex characteristics/development and produce estrogen/progesterone (in females - ovaries) and testosterone (in male - testes)






15. Involved in the effects of odors/pheromones in reproductive behavior - a nucleus that receives olfactory information from the olfactory bulb and accessory olfactory bulb






16. Cells that integrate information across the retina; rather than sending signals toward the brain - amacrine cells link bipolar cells to other bipolar cells and ganglion cells to other ganglion cells






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






18. Referred to as the satiety center; lesions lead to obesity and hyperphagia






19. Colored part of the eye






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






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






22. Is found between the dura mater and arachnoid mater meninges






23. Includes comparative (evolution/genetics/animal behavior/ethology) and behavioral regulation






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






25. 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)






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






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






28. Oculomotor Nerve - moves eye pupil






29. Abducens Nerve - moves eye






30. 'covering'






31. Skin senses that register the sensations of pressure - warmth and cold






32. Precursor to the catecholamine neurotransmitters (DA + NE)






33. 'Roof'






34. Vestibulocochlear Nerve - hearing and balance






35. Trochlear Nerve - moves eye






36. Hormones that reduce pain






37. Projects to ventral tegmental area






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






39. The maintenance of water balance in the body






40. Can occur after long term antipsychotic tx (opposite of Parkinson'S?); oversensitivity to dopamine






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






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






43. An inherited form of defective color vision in which hues with short wavelengths are confused (blue cone dysfunction); see world in green and red






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






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






46. Occurs intermittently during early stages of slow-wave sleep and REM sleep 3.5-7.5 Hz






47. Smooth electrical activity of 8-12 Hz -medium frequency - awake but in a restful state (^ eyes closed but conscious)






48. Serotonin = 5-HT -regulation of mood - anxiety - aggression - sleep - appetite - sexuality -rostral and caudal raphe nuclei






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






50. Functions in metabolism (carbohydrate - protein - lipid) and in the endocrine system'S salt/water balance - produces the hormones cortisol and aldosterone
