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 used to treat Parkinson'S Disease






2. Includes the tectum and tegmentum






3. Symptom of narcolepsy - irresistible urge to






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






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






6. Pass the easiest through the blood-brain barrier






7. 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






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






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






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






11. EEG desynchrony (rapid -irregular waves) - lack of muscle tonus - rapid eye movements - penile erection/vaginal secretion - dreams; EEG synchrony (slow waves) - moderate muscle tonus - slow/absent eye movements - lack of genital activity






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






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






14. 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

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






16. The Lee-Boot effect - Whitten effect - Vandenbergh effect - and the Bruce effect; all mediated by the VNO






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






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






19. 'covering'






20. Decreasing effects of a medication due to repeated administration






21. Made from within - natural






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






23. Is found in the frontal lobe (which is divided into the prefrontal lobes and ___ ___)






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






25. Physiologically different from the other four stages of sleep (i.e. the similarity between the summed electrical activity of neurons measured on the scalp (EEG) during REM sleep and during wakefulness






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






27. An axon of a neuron in one region of the brain whose terminals form synapses with neurons in another region






28. Transparent substance between lens and retina






29. Part of limbic system; protrusion of the bottom of the brain at the posterior end of the hypothalamus - contains some hypothalamic nuclei






30. Pleasure center of the brain; discovered by Olds & Milner






31. Those biological considerations which are IMMEDIATE;Behavioral/Cognitive Neuroscience (i.e. how the nervous and endocrine systems influence behaviors/thoughts)






32. In the CNS - is an amino acid that stabilizes neural activity






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






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






35. 1. ventral tegmentum to mesolimbic forebrain (cognition - reward systems - emotional behavior) 2. substantia nigra to caudate nucleus putamen (movement and sensory stimulation) 3. hypothalamus to pituitary gland (neuronal/hormonal control)






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






37. Located in the midbrain - a group of neurons which produce dopamine and degenerate in Parkinson'S Disease






38. Thymoleptics = relieves mania of bipolar disorder (lithium carbonate - valproic acid - carbamazepine)






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






40. Controls sexual activity






41. A steroid hormone produced by the ovary that maintains the endometrial lining of the uterus during the later part of the menstrual cycle and during pregnancy; along with estradiol it promotes receptivity in female mammals with estrous cycles






42. Portion of a sensory field to which a cell responds






43. Increasing effects/effectiveness of a medication due to repeated administration






44. Consummatory stimulus






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






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






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






48. Maintains balance/posture and coordinates body movements






49. In the tegmentum (ventral part of midbrain); its neurons connect to caudate nucleus + putamen (in basal ganglia)






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