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. Accessory Nerve - moves the head






2. Pass the easiest through the blood-brain barrier






3. Absolute; relative






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






5. 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






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






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






8. 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






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






10. Symptom of narcolepsy - irresistible urge to






11. Controls sexual activity






12. In the tegmentum (ventral part of midbrain); its neurons connect to caudate nucleus + putamen (in basal ganglia)






13. Vestibulocochlear Nerve - hearing and balance






14. 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






15. Opening in the iris; dilates and contracts allowing different levels of light in






16. 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






17. 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






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






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






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






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






22. Hypoglossal Nerve - moves the tongue






23. 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






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






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






26. 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






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






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






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






30. Occurs when a neuron is hyperpolarized and characterized by sufficient strength of stimulation triggering a new action potential






31. 1. ventral tegmentum to mesolimbic forebrain (cognition - reward systems - emotional behavior) 2. substantia nigra to caudate nucleus putamen (movement and sensory stimulation) 3. hypothalamus to pituitary gland (neuronal/hormonal control)






32. The maintenance of water balance in the body






33. The Lee-Boot effect - Whitten effect - Vandenbergh effect - and the Bruce effect; all mediated by the VNO






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






35. Also known as ABLATION - is any surgically induced brain lesion






36. Strip of limbic cortex lying along the lateral walls of the groove separating the cerebral hemispheres - just above the corpus callosum






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






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






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






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






41. Hypothalamic-pituitary-adrenal axis -controls stress response






42. Functions as both a hormone and a neurotransmitter in the brain






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






44. 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






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






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






47. 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






48. A BEHAVIOR; insistent urge of sleepiness forces us to seek sleep/a bad






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






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