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






2. Decreasing effects of a medication due to repeated administration






3. Is regulated by the hypothalamus






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






5. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in the nucleus accumbens - amygdala and hippocampus






6. Acetylcholine - glutamate - gamma-aminobutyric acid - dopamine - serotonin - norepinephrine - endorphin






7. First described by Descartes - a combination of antagonistic muscle movements (e.g. those involved in walking)






8. Consummatory stimulus






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






10. The visual image of the world on the retina






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






12. If head is rotated - eye movements occur in the same direction






13. These cells perform a variety of functions but do not transmit information; one type forms the myelin sheath






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






15. Similarity of alleles for a trait in an organism (i.e. heterozygous or homozygous)






16. Located underneath the cerebral cortex and includes the bottom portion of the forebrain - cerebellum - basal ganglia - medulla - pons - midbrain - thalamus - hypothalamus - amygdala - hippocampus






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






18. Has neurons for reflexes






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






20. Is used to treat Parkinson'S Disease






21. AKA the striate cortex - located at the back of the brain - and contains the visual cortex






22. 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






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






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






25. hormone - secreted by the pituitary gland -signals the adrenal gland to secrete corticosteroid hormones -ACTH is a critical component of the HPA Axis that controls the stress response






26. Controls sexual activity






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






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






29. Can occur after long term antipsychotic tx (opposite of Parkinson'S?); oversensitivity to dopamine






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






31. An anterograde amnesia in which one cannot form episodic memories BUT in experiments - patients that cannot identify previously heard melodies do show a preference for them -> explicit memory function has a different neurological basis than implicit

32. Important to motor system






33. Irregular electrical activity of 13-30 Hz - state of arousal - attentive






34. Is characteristic of indirect antagonist drugs






35. Cumulative effects of repeated stimulation from a presynaptic neuron






36. Supernormal






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






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






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






40. 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






41. Symptom of narcolepsy - irresistible urge to






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






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






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






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






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






47. Damage to this are causes clumsiness and loss of balance






48. A chemical released by one animal that affects the behavior or physiology of another animal; usually smelled or tasted






49. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)






50. Includes the tectum and tegmentum
