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






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






3. Projects to ventral tegmental area






4. Is found in the interior rostral temporal lobe - part of limbic system






5. Regulates body temperature






6. Occurs for body temperature - blood glucose levels - blood concentration - etc -hormones are important






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






8. Follow Hering'S Opponent Process of color vision - and only have two types: red-green and yellow-blue; other levels of color vision are tri-chromatic






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






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






11. Reduces anxiety - released with NE in amygdala - hippocampus - basal ganglia - periaqueductal gray region - locus coeruleus and PFS; NPY is diminished in persons with PTSD/CPTSD and those exposed to chronic stress






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






13. Affect sex characteristics/development and produce estrogen/progesterone (in females - ovaries) and testosterone (in male - testes)






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






15. Most brain communications are with the opposite side of the body






16. Is characteristic of indirect antagonist drugs






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






18. Adenine - Guanine - Thymine - Cytosine






19. An inherited form of defective color vision in which hues with short wavelengths are confused (blue cone dysfunction); see world in green and red






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






21. Sleepwalking - sleep talking






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






23. Include tolerance (possible withdrawal) and sensitivity






24. Those biological considerations which are IMMEDIATE;Behavioral/Cognitive Neuroscience (i.e. how the nervous and endocrine systems influence behaviors/thoughts)






25. 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






26. 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






27. 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






28. Portion of a sensory field to which a cell responds






29. One of the primary noradrenergic nuclei whose ascending axons project to frontal cortex - thalamus - hypothalamus - limbic system






30. Phantom limb pain - hypnotic induction and the success rate of placebo treatments






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






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






33. Pass the easiest through the blood-brain barrier






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






35. ...






36. Is an oversensitivity to dopamine (D2)






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






38. Is a receptor blocker; binds with a receptor but does not activate it - actually prevents the natural ligand from binding with the receptor






39. Vagus Nerve - heart rate and digestion






40. In the posterior frontal lobe - contains the somatosensory cortex (touch - pressure - temperature - pain)






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






42. Facial Nerve - moves face and salivates






43. Symptom of narcolepsy; complete paralysis that occurs while AWAKE/conscious; will suddenly fall to floor paralyzed for a few minutes






44. Tremors - rigidity of limbs - poor balance and difficulty initiating movements

45. Bunch of dopaminergic neurons starting in the substantia nigra and ending in the neostriatum






46. Made from within - natural






47. 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






48. Produce drowsiness and sleepiness






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






50. Midbrain - medulla and the pons
