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. 'little brain'






2. Auditory receptor cells in the cochlea that turn sound vibrations -> neural impulses






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






4. Are found in the diencephalon






5. A drug that facilitates the effects of a particular neurotransmitter on the postsynaptic cell






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






7. 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






8. Moving forward






9. Sleep tests (i.e. to diagnosis sleep apnea)






10. Absolute; relative






11. Pass the easiest through the blood-brain barrier






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






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






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






15. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)






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






17. The female reproductive cycle of mammals other than primates






18. The visual image of the world on the retina






19. Has neurons for reflexes






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






21. Caudate nucleus and putamen






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






23. Found in the hypothalamus - function to maintain the water balance in the body






24. The viscous substance between cornea and lens






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






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






27. Thymoleptics = relieves mania of bipolar disorder (lithium carbonate - valproic acid - carbamazepine)






28. Transparent substance between lens and retina






29. Forebrain -band of nerve fibers connecting the two cerebral hemispheres






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






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






32. Hormones that reduce pain






33. 1. Stage I (non-REM sleep) 2. Stage II (non-REM sleep 3. Stage III (non-REM sleep - slow-wave sleep) 4. Stage IV (non-REM sleep - slow-wave sleep) 5. Rapid Eye Movement Sleep (REM sleep) ~takes about 90 minutes for one full sleep cycle






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






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






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






37. 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






38. Synchronized EEG activity during its deeper stages






39. Sign






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






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






42. Produce drowsiness and sleepiness






43. The midbrain; a region that surrounds the cerebral aqueduct; includes tectum and the tegmentum






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






45. A 90-minute activity cycle occurs throughout the day as well as throughout sleep (in humans) waxing and waning alertness controlled by a biological clock in the caudal brainstem that also controls cycles of REM and slow-wave sleep






46. Produces acetylcholine. One of the earliest sites of cell death in Alzheimer'S Disease (neurological disorder associated with a deficiency in acetylcholine) is in the basal forebrain






47. Has a major role in metabolism - stimulation/maintenance - produces the hormones thyroxin and calcitonin






48. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






49. Is regulated by the hypothalamus






50. Located underneath the cerebral cortex and includes the bottom portion of the forebrain - cerebellum - basal ganglia - medulla - pons - midbrain - thalamus - hypothalamus - amygdala - hippocampus
