LA JOLLA?Light touch plays a critical role in everyday tasks, such as picking up a glass or playing a musical instrument. The sensation is also an essential part of the body?s protective defense system, alerting us to objects in our environment that could cause us to fall or injure ourselves. In addition, it is part of the detection system that has evolved to protect us from biting insects, such as those that cause malaria and Lyme disease, by eliciting a feeling of an itch when an insect lands on your skin.
