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. All have similar molecular structure - so many 'dirty' medications






2. Has neurons for reflexes






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






4. An area that combines input from diverse brain regions






5. The restorative effect of introducing a new female sex partner to a male that has apparently become 'exhausted' by sexual activity






6. Symptom of narcolepsy - irresistible urge to






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






8. EEG desynchrony (rapid -irregular waves) - lack of muscle tonus - rapid eye movements - penile erection/vaginal secretion - dreams; EEG synchrony (slow waves) - moderate muscle tonus - slow/absent eye movements - lack of genital activity






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






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






11. Is increased in its production by training/experience and therefore - associated with memory






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






13. Receptors whose activation directly affects potassium or chloride ion channels in the neuron - (many drugs of abuse substitute for natural GABA- alcohol - benzos - barbituates






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






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






16. Trochlear Nerve - moves eye






17. Relays nerve impulses - processes sensory impulses - reflex behavior and contains nerve cell bodies






18. Transparent substance between lens and retina






19. Self-dissolving






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






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






22. 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


23. 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)






24. 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)






25. Accessory Nerve - moves the head






26. Colored part of the eye






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






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






29. 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)






30. 'covering'






31. Has a calcium-related role and produces the hormone parathyroid






32. Include the Nigrostriatal system - Mesolimbic system and Mesocortical system






33. 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






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






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






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






37. A behavior that has different forms or occurs with different probabilities or under different circumstances in males than females






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






39. 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






40. 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)






41. Occurs under drug-induced conditions - including excessive use of marijuana; high body temperature - autonomic instability and muscle rigidity






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






43. Supernormal






44. Projects to ventral tegmental area






45. The maintenance of water balance in the body






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






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






48. 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






49. SCN = controls circadian rhythms - located directly above the optic chasm in the anterior portion of the hypothalamus - receives input from the eyes which is why light exposure affects our sleep-wake cycles






50. A drug that facilitates the effects of a particular neurotransmitter on the postsynaptic cell
