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. Has two lobes that are connected by the massa intermedia (looks like a pair of balls - without the nutsack)






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






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






4. Those biological considerations which are DISTANT; Evolutionary Psychology - Comparative Psychology - Ethology






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






6. Has neurons for reflexes






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






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






9. Physiologically different from the other four stages of sleep (i.e. the similarity between the summed electrical activity of neurons measured on the scalp (EEG) during REM sleep and during wakefulness






10. 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






11. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






12. Is an oversensitivity to dopamine (D2)






13. Attaches to the binding site on a receptor and interferes with the receptor'S action - but NOT by interfering with the principal ligand'S binding site (noncompetitive binding)






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






15. Accessory Nerve - moves the head






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






17. Ventral part of midbrain - includes periaqueductal gray matter - reticular formation - red nucleus - and substantia nigra






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






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






20. Is used to treat Parkinson'S Disease






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






22. Part of limbic system; protrusion of the bottom of the brain at the posterior end of the hypothalamus - contains some hypothalamic nuclei






23. Midbrain - medulla and the pons






24. Found in the ventricles and spinal canal






25. 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






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






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






28. Is regulated by the hypothalamus






29. Vision: protrusions on top of the midbrain; part of visual system






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






31. Cumulative effects of repeated stimulation from a presynaptic neuron






32. These two brain structures contain entry/exits for most of the cranial nerves and control vital functions (heart rate -digestion - respiration)






33. Moving forward






34. Abducens Nerve - moves eye






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






36. Occurs at the onset of puberty; a hypothalamic hormone that stimulates the pituitary gland to secrete gonadotropin






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






38. Made from within - natural






39. Convoluted of hills (gyri) and valleys (sulci) divided into two hemispheres (left and right) which are further divided into four lobes (occipital - parietal - temporal and frontal)






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






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






42. Optic Nerve - sight






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






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






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






46. The female reproductive cycle of mammals other than primates






47. Oculomotor Nerve - moves eye pupil






48. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)






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






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