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






2. ...






3. Decreasing effects of a medication due to repeated administration






4. Hypoglossal Nerve - moves the tongue






5. Is found in the frontal lobe (which is divided into the prefrontal lobes and ___ ___)






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






7. If head is rotated - eye movements occur in the same direction






8. Focuses light waves on the retina and is held in place by the suspensory ligament; aqueous humor on cornea side; vitreous humor on retina side






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






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






11. Can occur after long term antipsychotic tx (opposite of Parkinson'S?); oversensitivity to dopamine






12. Result in either tolerance (and possible withdrawal symptoms) or sensitization (increase effectiveness of the drug)






13. A steroid hormone produced by the ovary that maintains the endometrial lining of the uterus during the later part of the menstrual cycle and during pregnancy; along with estradiol it promotes receptivity in female mammals with estrous cycles






14. An area that combines input from diverse brain regions






15. 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






16. Cumulative effects of repeated stimulation from a presynaptic neuron






17. Suggests that dreams are nothing more than the product of random electrical impulses (Hobson & McCarley)






18. Motor neurons found in the Somatic (voluntary) and Autonomic (involuntary) Nervous Systems






19. Increasing effects/effectiveness of a medication due to repeated administration






20. Projects to ventral tegmental area






21. 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






22. Optic Nerve - sight






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






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






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






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






27. Sign






28. Midbrain - medulla and the pons






29. Pleasure center of the brain; discovered by Olds & Milner






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






31. The female reproductive cycle of mammals other than primates






32. Trigerminal Nerve - face sensation






33. 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






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






35. The increase in REM sleep seen after a period of REM sleep deprivation






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






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






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






39. 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)






40. Occurs during the deepest stages of slow-wave sleep; regular - synchronous electrical activity of less than 4 Hz






41. There are 12 add more






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






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






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






45. Synchronized EEG activity during its deeper stages






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






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






48. Precursor to GABA (the most inhibitory/regulatory/pervasive neurotransmitter)






49. 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






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