The power of touch — understanding the science
How does the sense of touch really work?
The main job of these receptors is to protect the body. For example, if the receptors send a signal that you are in pain or too cold, the brain then responds with an appropriate reaction. This may be to curl in a ball away from the pain or to make your body start shivering in response to the temperature.

The somatosensory system in practice
The somatosensory system allows us to experience touch, pain, pressure, heat and movement. This system relies on a network of sensors throughout the body, which are activated when there is heat or pressure against them.
So that your body knows what is going on at different areas, these sensors send information back to the brain by means of neurons. In turn, these send signals up the spinal cord to the brain.Once there, the brain decodes the messages to understand what sensations are being felt: pain, touch or temperature.
