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. If a synapse is active at about the same time that a postsynaptic neuron is active - that synapse will be strengthened






2. 'little brain'






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






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






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






6. Follow Hering'S Opponent Process of color vision - and only have two types: red-green and yellow-blue; other levels of color vision are tri-chromatic






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






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






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






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






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






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






13. Hormones that reduce pain






14. Having two copies of each chromosomes in most cells (except the gametes) - e.g. most mammals






15. Glossopharyngeal Nerve - taste swallow






16. 'covering'






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






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






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






20. Thymoleptics = relieves mania of bipolar disorder (lithium carbonate - valproic acid - carbamazepine)






21. Found that developmental changes occurring in puberty make the brain more susceptible to the psychotic effects of NDMA antagonist and therefore also related to the emergence of symptoms of schizophrenia






22. The viscous substance between cornea and lens






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






24. 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)






25. Trochlear Nerve - moves eye






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






27. Are postsynaptic potentials that are found in the dendrites and vary in their intensity






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






29. Is found at the base of the brain - underneath the thalamus (**remember hypo-below)






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






31. A patient who had intact intelligence but an inability to learn/remember anything new (severe anterograde amnesia)






32. Includes the thalamus and hypothalamus; region of forebrain surrounding the 3rd ventricle






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






34. Is used to treat Parkinson'S Disease






35. Optic Nerve - sight






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






37. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






38. Absolute; relative






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






40. Has neurons for reflexes






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






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






43. Controls sexual activity






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






45. Readiness with which molecules/drugs/medications join together; varies widely from medication to medication






46. 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






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






48. 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)






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






50. Made from within - natural
