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






2. Receive incoming sensory information or send out motor impulse commands






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






4. Glossopharyngeal Nerve - taste swallow






5. Portion of a sensory field to which a cell responds






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






7. Include tolerance (possible withdrawal) and sensitivity






8. 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)






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






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






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






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






13. 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






14. Occurs when their is damage to the septal area and results in unchecked aggressive and vicious behavior






15. Motor neurons found in the Somatic (voluntary) and Autonomic (involuntary) Nervous Systems






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






17. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






18. 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






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






20. Pass the easiest through the blood-brain barrier






21. 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






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






23. Part of a glial cell that wraps around the axon of a neuron - providing insulation that facilitates speed of propagation of action potential






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






25. Are postsynaptic potentials that are found in the dendrites and vary in their intensity






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






27. Vagus Nerve - heart rate and digestion






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






29. The female reproductive cycle of mammals other than primates






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






31. The visual image of the world on the retina






32. Hypothalamic-pituitary-adrenal axis -controls stress response






33. Moving forward






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






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






36. The synchronization of the menstrual or estrous cycles of a group of females - which occurs only in the presence of a pheromone in a male'S urine






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






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






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






40. Also known as ABLATION - is any surgically induced brain lesion






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






42. Is a loss of dopamine cells in the substantia nigra of the basal ganglia; these cells are usually dark (nigra) but in Parkinson'S - the substantia nigra appears white due to cell death

43. Abducens Nerve - moves eye






44. Consummatory stimulus






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






46. 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)

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






48. Hormones that reduce pain






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






50. 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
