Violent Video Games and the P300: No Evidence to Support the Neural Desensitization Hypothesis.

It has been proposed that exposure to violent video games (VVGs) resulted in alterations of social behaviors such as increased aggression. The most damaging reported effect of playing VVGs is neural desensitization to violent stimuli and this is a major concern given the reported number of players and time spent playing major video game titles. The aim of this study was to investigate the existence of neural desensitization that was reported at the P300 component of event-related potentials (ERPs) in response to violent stimuli.

Direct, continuous behavioral analysis of drug action on feeding.

Analysis of rodent feeding behavior during the study of anorectic drugs reveals that contextual variables such as type of food, drug, environment, and physiological state influence food intake. Temporal changes in behavior can signal the onset of a feeding modulation process, as is the case with anorectic drugs acting on distinct neurochemical mechanisms that change temporal behavioral profiles. Comparing the effects of anorectic agents in controlled animal assays can identify potential therapeutic drugs that may influence human eating behavior.
