Without looking, choose clothing, shoes, and so on, with matching or contrasting textures. For example, make it a silky, smooth day or a rough, nubby day. Use not only your fingers but also your cheeks, lips, and even your feet—they're all packed with receptors for fine touch.Extensive practice using the fingers to make fine distinctions between objects or textures causes the expansion and rewiring of the brain areas involved in touch. This has been observed in monkeys trained to use their fingers to get food and in brain imaging experiments in blind human Braille readers.
Research has shown that this type of exercise can result in a rapid and substantial expansion of circuits in the parts of the cortex that control and process tactile information from the hand.
