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. The visual image of the world on the retina






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






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






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






5. Abducens Nerve - moves eye






6. Located in the forebrain - basal ganglia -> movement -speech and other complex behaviors






7. 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






8. Holds the lens in place






9. Are found in the diencephalon






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






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






12. Colored part of the eye






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






14. Occurs when their is damage to the septal area and results in unchecked aggressive and vicious behavior






15. Is a loss of dopamine cells in the substantia nigra of the basal ganglia; these cells are usually dark (nigra) but in Parkinson'S - the substantia nigra appears white due to cell death


16. Fluid filled cavities in the middle of the brain - linking to the spinal canal that runs down the middle of the spinal cord; this fluid is cerebrospinal fluid






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






18. Skin senses that register the sensations of pressure - warmth and cold






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






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






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






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






23. All have similar molecular structure - so many 'dirty' medications






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






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






26. 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






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






28. Produce drowsiness and sleepiness






29. When a neuron reaches its excitation threshold - the neuron will produce an action potential of FIXED amplitude regardless of the magnitude of the stimulation






30. A region of the visual association cortex located in the extrastriate cortex at the base of the brain that has special face-recognizing circuits (more important in right hemisphere)






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






32. 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






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






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






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






36. Pass the easiest through the blood-brain barrier






37. Decreasing effects of a medication due to repeated administration






38. Associated with (spoken) language reception/comprehension - memory processing - and emotional control; contains Wernicke'S area and the auditory cortex






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






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






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






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






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






44. Made from within - natural






45. Measure changes in the electrical resistance of the skin (sweat gland activity)






46. Binding of drug to receptor site that doesn'T interfere with the principal ligand






47. 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






48. 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






49. Has neurons for reflexes






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