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. Links the nervous system and endocrine system; comprised of involuntary efferent neurons and divided into the Sympathetic and Parasympathetic branches: Sympathetic Nervous System is involved in the 'fight or flight' response and the Parasympathetic N






2. Convoluted of hills (gyri) and valleys (sulci) divided into two hemispheres (left and right) which are further divided into four lobes (occipital - parietal - temporal and frontal)






3. Important to motor system






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






5. Decreasing effects of a medication due to repeated administration






6. Binding of a drug to a receptor site that does not interfere with the binding site for the principal ligand






7. Norepinephrine and serotonin






8. 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)






9. Occurs intermittently during early stages of slow-wave sleep and REM sleep 3.5-7.5 Hz






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






11. 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






12. 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)






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






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






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






16. Increases heartrate - dilates/constricts blood vessels - increases blood sugar - produces hormones epinephrine and norepinephrine






17. Measure changes in the electrical resistance of the skin (sweat gland activity)






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






19. 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






20. The Lee-Boot effect - Whitten effect - Vandenbergh effect - and the Bruce effect; all mediated by the VNO






21. 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)






22. Located underneath the cerebral cortex and includes the bottom portion of the forebrain - cerebellum - basal ganglia - medulla - pons - midbrain - thalamus - hypothalamus - amygdala - hippocampus






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






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






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






26. If head is rotated - eye movements occur in the same direction






27. Optic Nerve - sight






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






29. The female reproductive cycle of mammals other than primates






30. Irregular electrical activity of 13-30 Hz - state of arousal - attentive






31. Has two lobes that are connected by the massa intermedia (looks like a pair of balls - without the nutsack)






32. An inherited form of defective color vision in which hues with short wavelengths are confused (blue cone dysfunction); see world in green and red






33. Moving forward






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






35. Research indicates that the expressing of negative emotions is associated with increased immune function; inhibiting negative emotions with decreasing immune function






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






37. Receptors whose activation directly affects potassium or chloride ion channels in the neuron - (many drugs of abuse substitute for natural GABA- alcohol - benzos - barbituates






38. EEG desynchrony (rapid -irregular waves) - lack of muscle tonus - rapid eye movements - penile erection/vaginal secretion - dreams; EEG synchrony (slow waves) - moderate muscle tonus - slow/absent eye movements - lack of genital activity






39. Symptom of narcolepsy - irresistible urge to






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






41. Lens changes initiated by the ciliary muscles to change the shape of the lens in order to focus image on the retina






42. An area that combines input from diverse brain regions






43. 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






44. Bunch of dopaminergic neurons starting in the substantia nigra and ending in the neostriatum






45. 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






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






47. Is found in PTSD/CPTSD patients and persons exposed to chronic stress






48. Skin senses that register the sensations of pressure - warmth and cold






49. There are 12 add more






50. Is used to treat Parkinson'S Disease
