Incoming sensory information can affect the brain’s structure, which may in turn affect the body’s motor output. However, the specifics of this process are not always well understood. In a recent study published in Scientific Reports, researchers from Tokyo Medical and Dental University (TMDU) found that when young rats were fed a diet of either soft or regular food, these different sensory inputs led to differences in muscle control and electrical activity of the jaw when a specific chewing-related brain region was stimulated.
