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 increased in its production by training/experience and therefore - associated with memory






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






3. The visual image of the world on the retina






4. Important to motor system






5. Cumulative effects of repeated stimulation from a presynaptic neuron






6. Precursor to the catecholamine neurotransmitters (DA + NE)






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






8. 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






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






10. Optic Nerve - sight






11. Is everything anterior to the central sulcus






12. Is generated by photoreceptors that are only sensitive to degrees of brightness; black-and-white vision found in the rods






13. Referred to as the satiety center; lesions lead to obesity and hyperphagia






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






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






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






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






18. These two developed the criteria for habituation; basic process is a form of synaptic depression that occurs presyntaptically.






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






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






21. Vestibulocochlear Nerve - hearing and balance






22. Symptom of narcolepsy - paralysis occurring just before a person falls alseep






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






24. Sign






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






26. Are postsynaptic potentials that are found in the dendrites and vary in their intensity






27. Is characteristic of indirect antagonists






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






29. The maintenance of water balance in the body






30. Glossopharyngeal Nerve - taste swallow






31. Instead of one continuum for sex (masculine-feminine) - her work in the presence of both masculine and feminine features/development suggests these are actually two separate continuums (defeminized-feminized and unmasculinized-masculinized)

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






33. Cells that integrate information across the retina; rather than sending signals toward the brain - amacrine cells link bipolar cells to other bipolar cells and ganglion cells to other ganglion cells






34. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






35. Trigerminal Nerve - face sensation






36. Short bursts of waves 12-14 Hz that occur 2-5 times a minute during stages 1-4 of sleep; most characteristic of sleep Stage II; some believe sleep spindles are involved in keeping one asleep (decline in older people)






37. Trochlear Nerve - moves eye






38. 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






39. Most pervasive excitatory neurotransmitter in the brain






40. Some brain communications are with the same side of the body






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






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






43. The viscous substance between cornea and lens






44. Precursor to GABA (the most inhibitory/regulatory/pervasive neurotransmitter)






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






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






47. Links the nervous system and endocrine system; comprised of involuntary efferent neurons and divided into the Sympathetic and Parasympathetic branches: Sympathetic Nervous System is involved in the 'fight or flight' response and the Parasympathetic N






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






49. Accessory Nerve - moves the head






50. Controls sexual activity; lesions inhibit sexual behavior; stimulation increases aggressive sexual behavior
