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. ...






2. 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)






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






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






5. Regulates body temperature






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






7. Sign






8. The maintenance of water balance in the body






9. 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






10. Attaches to the binding site on a receptor and interferes with the receptor'S action - but NOT by interfering with the principal ligand'S binding site (noncompetitive binding)






11. Oculomotor Nerve - moves eye pupil






12. One of the primary noradrenergic nuclei whose ascending axons project to frontal cortex - thalamus - hypothalamus - limbic system






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






14. An axon of a neuron in one region of the brain whose terminals form synapses with neurons in another region






15. An ovary or teste






16. Transparent substance between lens and retina






17. Trigerminal Nerve - face sensation






18. Precursor to GABA (the most inhibitory/regulatory/pervasive neurotransmitter)






19. 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)






20. Hormone secreted during the night by the pineal body; role in circadian and seasonal rhythms






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






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






23. Controls circadian rhythms - produces melatonin (daylight signals go to the eyes to the hypothalamus to the pineal gland)






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






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






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






27. Are found in the diencephalon






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






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






30. 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






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






32. Is characteristic of indirect antagonist drugs






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






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






35. Pleasure center of the brain; discovered by Olds & Milner






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






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






38. Sleepwalking - sleep talking






39. 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)






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






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






42. Holds the lens in place






43. Made from within - natural






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






45. A single - unfertilized cell created during conception; the combined egg + sperm






46. Colored part of the eye






47. Controls sexual activity; lesions inhibit sexual behavior; stimulation increases aggressive sexual behavior






48. The viscous substance between cornea and lens






49. The midbrain; a region that surrounds the cerebral aqueduct; includes tectum and the tegmentum






50. 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
