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






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






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






4. Comprised of the hypothalamus - pituitary gland - thyroid gland - parathyroid - the adrenal cortex - the adrenal medulla - the pancreas - the ovaries/testes - pineal gland.






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






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






7. Colored part of the eye






8. Decreasing effects of a medication due to repeated administration






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






10. A sensory organ that detects the presence of certain chemicals - especially when a liquid is actively sniffed; mediates the effects of some pheromones






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






12. ...






13. Found in the ventricles and spinal canal






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






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






16. Symptom of narcolepsy - paralysis occurring just before a person falls alseep






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






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






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






20. Self-dissolving






21. 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






22. 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






23. Sign






24. Is the primary inhibitory neurotransmitter in vertebrates; these receptors are ionotropic






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






26. 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)






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






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






29. 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)






30. Sleepwalking - sleep talking






31. Pass the easiest through the blood-brain barrier






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






33. A behavior that has different forms or occurs with different probabilities or under different circumstances in males than females






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






35. 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






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






37. Facial Nerve - moves face and salivates






38. Sits just above the hindbrain - contains cranial nerves - parts of the reticular formation -important relay stations for sensory information and the substantia nigra






39. Vestibulocochlear Nerve - hearing and balance






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






41. Hormone secreted during the night by the pineal body; role in circadian and seasonal rhythms






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






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






44. Involved in the effects of odors/pheromones in reproductive behavior - a nucleus that receives olfactory information from the olfactory bulb and accessory olfactory bulb






45. 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






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






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






48. Is characteristic of indirect antagonists






49. Abducens Nerve - moves eye






50. A drug that opposes/inhibits the effects of a particular neurotransmitter on the postsynaptic cell
