Over ten percent of the cerebral cortex is involved in dealing with information about the sense of touch — a larger area than previously thought – according to a joint study by researchers from the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig and Ruhr Universität Bochum. An encouraging pat on the… Read more

The sensation of taste includes five established basic tastes: sweetness, sourness, saltiness, bitterness, and umami. Scientific experiments have demonstrated that these five tastes exist and are distinct from one another. Taste buds are able to distinguish between different tastes through detecting interaction with different molecules or ions. Sweet, savory, and bitter tastes are triggered by… Read more

The answer to how your brain knows when you’ve had enough to drink and can stop feeling thirsty may have been found in a new UC San Francisco study. Until recently, scientists believed that a brain region called the hypothalamus makes us thirsty when it detects a drop in the hydration of our blood. But… Read more

Similarly, I have shown that chills are not solely related to music or film but also to the practice… Read more

A new study shows that higher-level regions of the brain may compensate for persistent reorganizational changes in brain areas responsible for hand sensation and movement following a hand transplant. When a person loses a hand, nerves that control sensation and movement are severed. This trauma deprives sensory and movement areas of the brain of stimulation… Read more
