What is the sense of touch?

Touch is a unified sensation created by many specialized sensors working together in parallel. If you look at your skin, described by neuroscientists as a Social Organ, it’s populated by millions of nerve endings that capture information from outside the body and then send it to the brain. Some nerves reach a specific part of the brain called the somatosensory cortex, also known as the discriminative system. This system gives us details of what we’re touching and where.
In addition to nerves reaching the somatosensory cortex, there are some nerves that travel to a completely different part of the brain called the posterior insular cortex. This area of the brain is part of our emotional system and is involved in our behavioral and emotional responses. Basically, what I want to say is that “there is no sensation without emotion”, your skin is your external nervous system.
When do we start to feel touch?

The sense of touch begins in the womb around the 8-week mark, and among the five senses (touch, taste, smell, hearing and sight), touch is the first to develop. Science has shown how it’s not just a matter of time but also, it’s a development priority; in fact, premature infants that are isolated in incubators exhibit a developmental delay, which is due to an inadequate or inappropriate sensory stimulation. But there’s more, it’s not just about biological development, touch deprivation in infants can lead to impaired growth and cognitive development, as well as an elevated incidence of serious infections and attachment disorders.
Why is touch so important in our social life?

As mentioned at the beginning, some scientists have called the skin a “social organ.” Intuitively, this makes sense: we both crave touch and are repulsed by it when it is unwanted, uninvited, or inappropriate. Even brief touches on a hand or arm can have tremendous effects.
Human behaviours involving physical touch have much more in common with the social grooming activities we’d typically associate with other species. When monkeys pick through their friends’ fur, they’re not just helping them remove dirt and parasites from hard-to-reach spots. There is undoubtedly a hygienic benefit, but this behaviour, which animal behaviour researchers call “allogrooming”, has far greater significance. According to anthropologist Robin Dunbar, grooming stimulates the release of endorphins – opiates produced by the brain that trigger feelings of relaxation. This is accomplished by lowering the heart rate, reducing over-nervous behaviours like scratching, and even bringing on sleep. Touch reflects our culture; it regulates our social relationships and helps us communicate.
What’s the meaning of touch in my daily practice?

Touch is the core of my clinical practice because it’s a powerful form of communication. Hearing your story, getting a sense of what matters to you, and observing what is held in the tissues allow me to examine and trace where your body has been keeping the score.
Osteopathic Manual Practitioners are well known for their well-developed touch (palpation) and ability to assess, treat and monitor how the body has been adapting throughout your life. Thus, Osteopathic Treatment is based on the principles of body unity and the interrelationship between structure and function. This approach emphasizes the integration of the musculoskeletal system with the whole body, such as the visceral and craniosacral system, and the influences that the impaired function of each has on the other. Most Osteopathic Techniques aim to reduce tissue tension, help to improve motion, function, and flow of liquid and decrease neurological sensitization; the decision-making of which techniques to use is tailored to your needs to achieve better function.
