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






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






3. The maintenance of water balance in the body






4. 'Roof'






5. 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






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






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






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






9. Smooth electrical activity of 8-12 Hz -medium frequency - awake but in a restful state (^ eyes closed but conscious)






10. Serotonin = 5-HT -regulation of mood - anxiety - aggression - sleep - appetite - sexuality -rostral and caudal raphe nuclei






11. 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)






12. Abducens Nerve - moves eye






13. Governs eating/drinking (lateral and ventromedial hypothalami) and sexual activity (anterior portion






14. 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






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






16. Consummatory stimulus






17. Relays nerve impulses - processes sensory impulses - reflex behavior and contains nerve cell bodies






18. Occurs under drug-induced conditions - including excessive use of marijuana; high body temperature - autonomic instability and muscle rigidity






19. Referred to as the satiety center; lesions lead to obesity and hyperphagia






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. Is found between the dura mater and arachnoid mater meninges






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






23. Is regulated by the hypothalamus






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






25. Vagus Nerve - heart rate and digestion






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






27. There are 12 add more






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






29. Hormones that reduce pain






30. Found in the ventricles and spinal canal






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






32. Activates one of 5 types of receptors in the CNS - cognition - motor activity - reward - muscle tone - sleep - mood - attention - learning -higher level effects of dopamine = D2






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






34. Contains receptors to detect when the body needs food or fluids; the hunger center; lesions lead to aphagia






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






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






37. A patient who had intact intelligence but an inability to learn/remember anything new (severe anterograde amnesia)






38. Are found in the diencephalon






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






40. These two developed the criteria for habituation; basic process is a form of synaptic depression that occurs presyntaptically.






41. learning and memory -neurotransmitter released at the neuromuscular junction of skeletal muscle axons to excite the muscle to contract






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






43. Associated with (spoken) language reception/comprehension - memory processing - and emotional control; contains Wernicke'S area and the auditory cortex






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






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






46. 'little brain'






47. The restorative effect of introducing a new female sex partner to a male that has apparently become 'exhausted' by sexual activity






48. 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






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






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