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. Is characteristic of indirect antagonist drugs






2. These two brain structures contain entry/exits for most of the cranial nerves and control vital functions (heart rate -digestion - respiration)






3. A single - unfertilized cell created during conception; the combined egg + sperm






4. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






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






6. 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






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






8. 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






9. 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






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






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






12. An area that combines input from diverse brain regions






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






14. These two developed the criteria for habituation; basic process is a form of synaptic depression that occurs presyntaptically.






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






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






17. 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)






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






19. Located underneath the cerebral cortex and includes the bottom portion of the forebrain - cerebellum - basal ganglia - medulla - pons - midbrain - thalamus - hypothalamus - amygdala - hippocampus






20. Contains delta activity - stages III and IV






21. Norepinephrine and serotonin






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






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






24. 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






25. The scientific study of animal behavior; documentation of species-specific instinctual behaviors






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






27. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






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






29. Occurs when their is damage to the septal area and results in unchecked aggressive and vicious behavior






30. 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






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






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






33. Mechanism whereby neurons make connections to new areas to change their connectivity






34. Physiologically different from the other four stages of sleep (i.e. the similarity between the summed electrical activity of neurons measured on the scalp (EEG) during REM sleep and during wakefulness






35. Extensive research in dreams - said BAH to Freud; proposed the activation-synthesis hypothesis (dreams are nothing more than the product of random electrical impulses)






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






37. Optic Nerve - sight






38. Is generated by photoreceptors that are only sensitive to degrees of brightness; black-and-white vision found in the rods






39. Maintains balance/posture and coordinates body movements






40. Lesions to this brain structure that is crucial to memory will produce anterograde amnesia






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






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






43. 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)






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






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






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






47. Facial Nerve - moves face and salivates






48. Controls sexual activity






49. Projects to ventral tegmental area






50. An ovary or teste
