In a study that casts light on the process of choosing between alternative eye movements, researchers at Imperial College London have demonstrated that the medial frontal cortex, an area of the brain previously implicated in controlling actions and making choices, respond...ASU researchers finds novel chemistry at work to provide parrot's vibrant red colors
