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






2. 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)






3. Adenine - Guanine - Thymine - Cytosine






4. Is everything anterior to the central sulcus






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






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






7. 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)






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






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






10. Self-dissolving






11. Fluid filled cavities in the middle of the brain - linking to the spinal canal that runs down the middle of the spinal cord; this fluid is cerebrospinal fluid






12. Occurs during the deepest stages of slow-wave sleep; regular - synchronous electrical activity of less than 4 Hz






13. Two different presynaptic neurons/inputs to a post-synaptic cell






14. Thymoleptics = relieves mania of bipolar disorder (lithium carbonate - valproic acid - carbamazepine)






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






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






17. Has neurons for reflexes






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






19. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)






20. Projects to ventral tegmental area






21. Glossopharyngeal Nerve - taste swallow






22. Pass the easiest through the blood-brain barrier






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






24. Instead of one continuum for sex (masculine-feminine) - her work in the presence of both masculine and feminine features/development suggests these are actually two separate continuums (defeminized-feminized and unmasculinized-masculinized)

25. Midbrain - medulla and the pons






26. Expression of traits






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






28. 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)






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






30. 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






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






32. Forebrain -band of nerve fibers connecting the two cerebral hemispheres






33. Is found in the interior rostral temporal lobe - part of limbic system






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






35. Absolute; relative






36. Occurs for body temperature - blood glucose levels - blood concentration - etc -hormones are important






37. Actually are two kinds: monochorionic and dichorionic (blastocyst splis into two before day 4)






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






39. Has a major role in metabolism - stimulation/maintenance - produces the hormones thyroxin and calcitonin






40. Is characteristic of indirect antagonist drugs






41. Accessory Nerve - moves the head






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






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






44. 'Roof'






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






46. Norepinephrine and serotonin






47. Include tolerance (possible withdrawal) and sensitivity






48. Caudate nucleus and putamen






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






50. Consummatory stimulus
