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. A region of the visual association cortex located in the extrastriate cortex at the base of the brain that has special face-recognizing circuits (more important in right hemisphere)






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






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






4. Associated with (spoken) language reception/comprehension - memory processing - and emotional control; contains Wernicke'S area and the auditory cortex






5. Termination of pregnancy by the odor of a pheromone in the urine of a male other than the one that impregnated the female; first observed in mice






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






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






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






9. Is characteristic of indirect antagonists






10. Is characteristic of indirect antagonist drugs






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






12. A steroid hormone produced by the ovary that maintains the endometrial lining of the uterus during the later part of the menstrual cycle and during pregnancy; along with estradiol it promotes receptivity in female mammals with estrous cycles






13. Colored part of the eye






14. An ovary or teste






15. Transparent substance between lens and retina






16. Related to plasticity - the term Lashley used to describe different parts of the cortex being interchangeable in their roles in learning






17. 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

18. Produce drowsiness and sleepiness






19. The midbrain; a region that surrounds the cerebral aqueduct; includes tectum and the tegmentum






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






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






22. Controls sexual activity






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






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






25. Is found in PTSD/CPTSD patients and persons exposed to chronic stress






26. 'little net'






27. Maintains balance/posture and coordinates body movements






28. Stimulates bone growth and produces the hormones: somatotropin - prolactin - thyroid-stimulating - adrenocorticotropic (ACTH) - follicle-stimulating - luteinnizing






29. Neurotransmitter in CNS - hormone in peripheral vascular system; deficiencies > depression - ADD; noradrenergic nuclei = locus coeruleus






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






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






32. 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






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






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






35. Trochlear Nerve - moves eye






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






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






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






39. Acetylcholine - glutamate - gamma-aminobutyric acid - dopamine - serotonin - norepinephrine - endorphin






40. Is everything anterior to the central sulcus






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






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






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






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






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






46. Occurs when an external stimulation - regardless of intensity - will not trigger a new action potential






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






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






49. Phantom limb pain - hypnotic induction and the success rate of placebo treatments






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