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. Hormones that reduce pain






2. An area that combines input from diverse brain regions






3. hormone - secreted by the pituitary gland -signals the adrenal gland to secrete corticosteroid hormones -ACTH is a critical component of the HPA Axis that controls the stress response






4. Is found in the frontal lobe (which is divided into the prefrontal lobes and ___ ___)






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






6. Is an oversensitivity to dopamine (D2)






7. Tremors - rigidity of limbs - poor balance and difficulty initiating movements

8. Optic Nerve - sight






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






10. Affect sex characteristics/development and produce estrogen/progesterone (in females - ovaries) and testosterone (in male - testes)






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






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






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






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






15. Associated with defensive and aggressive behavior; lesions produce docility and hypersexual states (Kluver & Bucy)






16. Acquired language disorders - usually caused by damage in the left hemisphere; includes Broca'S: (left frontal lobe damage) and Wernickes'S (left temporal/parietal damage)






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






18. 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






19. Sign






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






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






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






23. Eating - sex - aggression - sleep - focus on subcortical and neuroendocrine control of behavior






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






25. A peptide - also known as OREXIN - produced by neurons whose cell bodies are located in the hypothalamus; their destruction causes narcolepsy






26. Holds the lens in place






27. Focuses light waves on the retina and is held in place by the suspensory ligament; aqueous humor on cornea side; vitreous humor on retina side






28. Found in the ventricles and spinal canal






29. Include tolerance (possible withdrawal) and sensitivity






30. Those biological considerations which are DISTANT; Evolutionary Psychology - Comparative Psychology - Ethology






31. 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






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






33. Midbrain - medulla and the pons






34. 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






35. Transparent substance between lens and retina






36. In the CNS - is an amino acid that stabilizes neural activity






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






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






39. Decreasing effects of a medication due to repeated administration






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






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






42. Decreases with age up until age 30 - then begins to increase *(counter intuitive)*






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






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






45. Consummatory stimulus






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






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






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






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






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