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 an oversensitivity to dopamine (D2)






2. Are found in the diencephalon






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






4. Symptom of narcolepsy - irresistible urge to






5. Abducens Nerve - moves eye






6. 'little brain'






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






8. Norepinephrine and serotonin






9. Controls sexual activity






10. Referred to as the satiety center; lesions lead to obesity and hyperphagia






11. Self-dissolving






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






13. Glandular system control center - produces the hormones oxytocin and antidiuretic; functions in both the nervous system and endocrine sytem - In the forebrain - regulates motivated behaviors (eating - drinking - aggression - sexual behavior






14. 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)






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






16. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in prefrontal cortex






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






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






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






20. 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)






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






22. Sleep tests (i.e. to diagnosis sleep apnea)






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






24. The slowing and eventual cessation of estrous cycles in groups of female animals that are housed together; caused by a pheromone in the animals urine and first observed in mice






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






26. Glossopharyngeal Nerve - taste swallow






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






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






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






30. Absolute; relative






31. Is a peptide neurotransmitter and a natural painkiller and antianxiety






32. Is regulated by the hypothalamus






33. Is used as an anaesthetic for children and animals but causes psychosis in adults






34. 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






35. When a neuron reaches its excitation threshold - the neuron will produce an action potential of FIXED amplitude regardless of the magnitude of the stimulation






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






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






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






39. Hypoglossal Nerve - moves the tongue






40. Include tolerance (possible withdrawal) and sensitivity






41. 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)






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






43. 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

44. Areas in the brain receiving incoming sensory information or sending out motor-impulse commands






45. Accessory Nerve - moves the head






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






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






48. Found in the hypothalamus - function to maintain the water balance in the body






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






50. Most pervasive excitatory neurotransmitter in the brain
