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. Readiness with which molecules/drugs/medications join together; varies widely from medication to medication






2. Synchronized EEG activity during its deeper stages






3. Sign






4. 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






5. Phantom limb pain - hypnotic induction and the success rate of placebo treatments






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






7. 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)






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






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






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






11. Olfactory Nerve - smell






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






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






14. Facial Nerve - moves face and salivates






15. 'Roof'






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






17. Lesions to this brain structure that is crucial to memory will produce anterograde amnesia






18. 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






19. 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)






20. Precursor to the catecholamine neurotransmitters (DA + NE)






21. Controls sexual activity






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






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






24. 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






25. Similarity of alleles for a trait in an organism (i.e. heterozygous or homozygous)






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






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






28. A chemical released by one animal that affects the behavior or physiology of another animal; usually smelled or tasted






29. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






30. Pass the easiest through the blood-brain barrier






31. An area that combines input from diverse brain regions






32. Found that developmental changes occurring in puberty make the brain more susceptible to the psychotic effects of NDMA antagonist and therefore also related to the emergence of symptoms of schizophrenia






33. 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)






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






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






36. 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






37. Completely disactivates the prefrontal cortex (PFC); due to high levels of norepinephrine (NE)






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






39. Choroid Plexus > Ventricle 1 & 2 > Foramen of Monro > Ventricle 3 > Aqueduct of Sylvius > Ventricle 4 > Foramen of Magendie lateral aperture) > Foramina of Luschka (lateral aperture) - subarachnoid space (outside of brain) and spinal cord > re-absorp






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






41. Adenine - Guanine - Thymine - Cytosine






42. Follow Hering'S Opponent Process of color vision - and only have two types: red-green and yellow-blue; other levels of color vision are tri-chromatic






43. Has neurons for reflexes






44. Are direct antagonists; binds with a receptor but does not activate it - but prevents the natural ligand from binding with the receptor






45. Expression of traits






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






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






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






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






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