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. The increase in REM sleep seen after a period of REM sleep deprivation






2. Include tolerance (possible withdrawal) and sensitivity






3. 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






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






5. First described by Descartes - a combination of antagonistic muscle movements (e.g. those involved in walking)






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






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






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






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






10. Is found between the arachnoid mater and Pia mater; this is where CSF cushions (and bathes) the brain - giving it the floating quality (and keeping it moist/circulating)






11. 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






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






13. Associated with (spoken) language reception/comprehension - memory processing - and emotional control; contains Wernicke'S area and the auditory cortex






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






15. Vision: protrusions on top of the midbrain; part of visual system






16. Occurs when a neuron is hyperpolarized and characterized by sufficient strength of stimulation triggering a new action potential






17. In the limbic system - is a fiber bundle - connects hippocampus with stuff (including the mammillary bodies of the hypothalamus)






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






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






20. Junction of the sagittal and coronal sutures of the skull; often used as a reference point for stereotaxic brain surgery






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






22. 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






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






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






25. 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






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






27. Projects to ventral tegmental area






28. 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






29. Emotional perception and expression (particularly fearful emotions and detection of threat)






30. Termination of pregnancy by the odor of a pheromone in the urine of a male other than the one that impregnated the female; first observed in mice






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






32. Includes comparative (evolution/genetics/animal behavior/ethology) and behavioral regulation






33. Is the primary inhibitory neurotransmitter in vertebrates; these receptors are ionotropic






34. Damage to this are causes clumsiness and loss of balance






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






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






37. Abducens Nerve - moves eye






38. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






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






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






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






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






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






44. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in the nucleus accumbens - amygdala and hippocampus






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






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






47. Combines input from diverse brain regions; receives sensory information/sends motor impulses






48. 'covering'






49. 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






50. Is regulated by the hypothalamus
