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. Forebrain -band of nerve fibers connecting the two cerebral hemispheres






2. Is regulated by the hypothalamus






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






4. Neurotransmitter in CNS - hormone in peripheral vascular system; deficiencies > depression - ADD; noradrenergic nuclei = locus coeruleus






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






6. The restorative effect of introducing a new female sex partner to a male that has apparently become 'exhausted' by sexual activity






7. Is found in the interior rostral temporal lobe - part of limbic system






8. Contains receptors to detect when the body needs food or fluids; the hunger center; lesions lead to aphagia






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






10. Choroid Plexus > Ventricle 1 & 2 > Foramen of Monro > Ventricle 3 > Aqueduct of Sylvius > Ventricle 4 > Foramen of Magendie lateral aperture) > Foramina of Luschka (lateral aperture) - subarachnoid space (outside of brain) and spinal cord > re-absorp






11. Occurs intermittently during early stages of slow-wave sleep and REM sleep 3.5-7.5 Hz






12. Are found in the diencephalon






13. Is characteristic of indirect antagonist drugs






14. Acquired language disorders - usually caused by damage in the left hemisphere; includes Broca'S: (left frontal lobe damage) and Wernickes'S (left temporal/parietal damage)






15. Oculomotor Nerve - moves eye pupil






16. 'little brain'






17. Projects to ventral tegmental area






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






19. 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






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






21. Expression of traits






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






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






24. The earlier onset of puberty seen in female animals that are housed with males caused by a pheromone in the male'S urine and first observed in mice






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






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






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






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






29. 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






30. Is used to treat Parkinson'S Disease






31. Decreasing effects of a medication due to repeated administration






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






33. Symptom of narcolepsy; complete paralysis that occurs while AWAKE/conscious; will suddenly fall to floor paralyzed for a few minutes






34. Are direct antagonists; binds with a receptor but does not activate it - but prevents the natural ligand from binding with the receptor






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






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






37. An area that combines input from diverse brain regions






38. Stimulates bone growth and produces the hormones: somatotropin - prolactin - thyroid-stimulating - adrenocorticotropic (ACTH) - follicle-stimulating - luteinnizing






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






40. Found in the hypothalamus - function to maintain the water balance in the body






41. Activates one of 5 types of receptors in the CNS - cognition - motor activity - reward - muscle tone - sleep - mood - attention - learning -higher level effects of dopamine = D2






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






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






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






45. 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)






46. Begins where spinal cord ends - 3 structures: the medulla - the pons - the cerebellum






47. Olfactory Nerve - smell






48. Colored part of the eye






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






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