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. Is everything anterior to the central sulcus






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






3. Moving forward






4. Midbrain - medulla and the pons






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






6. Occur in amacrine - bipolar and horizontal cells; govern/encompass the opponent-process level of color vision






7. Made from within - natural






8. Research indicates that the expressing of negative emotions is associated with increased immune function; inhibiting negative emotions with decreasing immune function






9. Extensive research in dreams - said BAH to Freud; proposed the activation-synthesis hypothesis (dreams are nothing more than the product of random electrical impulses)






10. ...






11. The slowing and eventual cessation of estrous cycles in groups of female animals that are housed together; caused by a pheromone in the animals urine and first observed in mice






12. Is regulated by the hypothalamus






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






14. 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






15. Colored part of the eye






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






17. Relays nerve impulses - processes sensory impulses - reflex behavior and contains nerve cell bodies






18. A single - unfertilized cell created during conception; the combined egg + sperm






19. 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






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






21. Termination of pregnancy by the odor of a pheromone in the urine of a male other than the one that impregnated the female; first observed in mice






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






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






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






25. Emotional perception and expression (particularly fearful emotions and detection of threat)






26. 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






27. Hormone secreted during the night by the pineal body; role in circadian and seasonal rhythms






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






29. Somewhat excitatory - also involved in synaptic plasticity - learning and short-term memory






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






31. Binding of a drug to a receptor site that does not interfere with the binding site for the principal ligand






32. Trigerminal Nerve - face sensation






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






34. Controls sexual activity






35. Pass the easiest through the blood-brain barrier






36. 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






37. Is found in PTSD/CPTSD patients and persons exposed to chronic stress






38. Adenine - Guanine - Thymine - Cytosine






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






40. Sits just above the hindbrain - contains cranial nerves - parts of the reticular formation -important relay stations for sensory information and the substantia nigra






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






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






43. 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

44. Regulates body temperature






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






46. 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)






47. Facial Nerve - moves face and salivates






48. Cornea - aqueous humor - pupil - lens - vitreous humor - retina






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






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