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. Sign






2. A drug that opposes/inhibits the effects of a particular neurotransmitter on the postsynaptic cell






3. A sensory organ that detects the presence of certain chemicals - especially when a liquid is actively sniffed; mediates the effects of some pheromones






4. Olfactory Nerve - smell






5. Completely disactivates the prefrontal cortex (PFC); due to high levels of norepinephrine (NE)






6. Has neurons for reflexes






7. Sits just above the hindbrain - contains cranial nerves - parts of the reticular formation -important relay stations for sensory information and the substantia nigra






8. Made from within - natural






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






10. Cumulative effects of repeated stimulation from a presynaptic neuron






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






12. Produces acetylcholine. One of the earliest sites of cell death in Alzheimer'S Disease (neurological disorder associated with a deficiency in acetylcholine) is in the basal forebrain






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






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






15. Sleepwalking - sleep talking






16. Oculomotor Nerve - moves eye pupil






17. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






18. 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






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






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






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






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






23. 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)






24. Adenine - Guanine - Thymine - Cytosine






25. Projects to ventral tegmental area






26. Is characteristic of indirect antagonists






27. Self-dissolving






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






29. Attaches to a binding site on receptor and interferes with the action of the receptor without affecting the binding site for the principal ligand (noncompetitive binding)






30. Found in the ventricles and spinal canal






31. Dorsal part of midbrain; includes the superior and inferior colliculi






32. Part of a glial cell that wraps around the axon of a neuron - providing insulation that facilitates speed of propagation of action potential






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






34. Begins where spinal cord ends - 3 structures: the medulla - the pons - the cerebellum






35. Cornea - aqueous humor - pupil - lens - vitreous humor - retina






36. Binding of a drug to a receptor site that does not interfere with the binding site for the principal ligand






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






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






39. Automatic and rapidly acquired reactions - not attributable to reinforcement or conditioning






40. Viscous substance between cornea and lens; transparent substance between lens and retina






41. In the limbic system - is a fiber bundle - connects hippocampus with stuff (including the mammillary bodies of the hypothalamus)






42. Controls sexual activity






43. Some brain communications are with the same side of the body






44. Maintains balance/posture and coordinates body movements






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






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






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






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






49. 'little brain'






50. 'little net'
