[Q]: One major pathway involving this compound is the tuberoinfundibular one that transfers it from the hypothalamus to the pituitary gland. This compound is involved in voluntary motor control via its nigriostriatal pathway, and it binds with lactotrophs in order to inhibit the secretion of prolactin, which is a major antagonist of it. It is the immediate precursor of norepinephrine in the epinephrine synthesis pathway. Antagonists of this neurotransmitter are used to treat schizophrenia, and deficiency of this neurotransmitter can lead to Parkinsons disease. For 10 points, name this neurotransmitter associated with the brain's pleasure center whose precursor is L-dopa.

FTP, identify this law that relates the vapor pressure and mole fraction of a solution, a law named for its French discoverer.
[A]: Science


[Q]: A key development of its early history was the discovery of an optical illusion in which two still images, flashed at an appropriate interval, would appear to a viewer to be in motion. This phi phenomenon was one of the first discoveries that led this school's founders to oppose previous atomistic views of perception. Its proponents' later work led to the formulation of several laws of organization that noted that humans tend to group items by proximity and similarity, fill in gaps in incomplete figures, and perceive multiple items in as simple a way as possible. Founded by Wertheimer, Kohler and Koffka, FTP, name this school of psychology characterized by emphasis on the whole rather the sum of parts.
