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. Facial Nerve - moves face and salivates






2. Symptom of narcolepsy; complete paralysis that occurs while AWAKE/conscious; will suddenly fall to floor paralyzed for a few minutes






3. Is everything anterior to the central sulcus






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






5. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)






6. Vagus Nerve - heart rate and digestion






7. A 90-minute activity cycle occurs throughout the day as well as throughout sleep (in humans) waxing and waning alertness controlled by a biological clock in the caudal brainstem that also controls cycles of REM and slow-wave sleep






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






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






10. These two brain structures contain entry/exits for most of the cranial nerves and control vital functions (heart rate -digestion - respiration)






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






12. When a neuron reaches its excitation threshold - the neuron will produce an action potential of FIXED amplitude regardless of the magnitude of the stimulation






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






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






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






16. 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)






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






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






19. An area that combines input from diverse brain regions






20. 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)

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






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






23. Refers to both the somatosensory cortex and motor cortex (they are a little different but very interrelated)






24. Cornea - aqueous humor - pupil - lens - vitreous humor - retina






25. Having two copies of each chromosomes in most cells (except the gametes) - e.g. most mammals






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






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






29. Absolute; relative






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






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






32. Glossopharyngeal Nerve - taste swallow






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






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






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






36. 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






37. 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






38. Is regulated by the hypothalamus






39. Include tolerance (possible withdrawal) and sensitivity






40. 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






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






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






43. Those biological considerations which are IMMEDIATE;Behavioral/Cognitive Neuroscience (i.e. how the nervous and endocrine systems influence behaviors/thoughts)






44. 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






45. Dorsal part of midbrain; includes the superior and inferior colliculi






46. Cells that integrate information across the retina; rather than sending signals toward the brain - amacrine cells link bipolar cells to other bipolar cells and ganglion cells to other ganglion cells






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






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






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






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