An anonymous reader writes: NBCUniversal's recently-opened Orlando neuroscience lab is trying to develop methods of delivering advertisements related to the scene in the show preceding them, such as delivering a food advertisement directly after a scene which has been shown to make test-subjects hungry. Viacom is building a lab right now to take electroencephalagrams of viewers while they watch. "And ratings firm Nielsen Holdings, which just bought neuroscience firm Innerscope Research earlier this year, is adding facial coding and biometrics to its labs, which currently conduct eye tracking and perform EEGs." NBC doesn't trust what viewers say when asked for their opinion on shows. They want to use science to determine which scenes trigger an emotional response, whether the viewer acknowledges it or not.
