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. Vestibulocochlear Nerve - hearing and balance






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






3. 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)






4. Stimulates bone growth and produces the hormones: somatotropin - prolactin - thyroid-stimulating - adrenocorticotropic (ACTH) - follicle-stimulating - luteinnizing






5. Is increased in its production by training/experience and therefore - associated with memory






6. 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






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






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






9. Holds the lens in place






10. The maintenance of water balance in the body






11. The slowing and eventual cessation of estrous cycles in groups of female animals that are housed together; caused by a pheromone in the animals urine and first observed in mice






12. Some brain communications are with the same side of the body






13. Maintains balance/posture and coordinates body movements






14. Self-dissolving






15. Vagus Nerve - heart rate and digestion






16. Junction of the sagittal and coronal sutures of the skull; often used as a reference point for stereotaxic brain surgery






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






18. Somewhat excitatory - also involved in synaptic plasticity - learning and short-term memory






19. Decreasing effects of a medication due to repeated administration






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






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






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






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






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






25. Occurs for body temperature - blood glucose levels - blood concentration - etc -hormones are important






26. Has a calcium-related role and produces the hormone parathyroid






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






28. Trochlear Nerve - moves eye






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






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






31. Found in the ventricles and spinal canal






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






33. Moving forward






34. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in prefrontal cortex






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






36. Is used as an anaesthetic for children and animals but causes psychosis in adults






37. Hypoglossal Nerve - moves the tongue






38. The earlier onset of puberty seen in female animals that are housed with males caused by a pheromone in the male'S urine and first observed in mice






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






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






41. Colored part of the eye






42. Actually are two kinds: monochorionic and dichorionic (blastocyst splis into two before day 4)






43. Located in the midbrain - a group of neurons which produce dopamine and degenerate in Parkinson'S Disease






44. Is a peptide neurotransmitter and a natural painkiller and antianxiety






45. 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






46. States that performance is worst at extremely low or extremely high levels of arousal and optimally at an intermediate level






47. Regulates body temperature






48. Olfactory Nerve - smell






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






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