Emotional and sensory components create a mosaic of activity influencing how we perceive pain. Some successful treatments target the emotional component like meditation, hypnosis, cognitive behavioral therapy, and the controlled use of cannabis. There is more to learn about how the brain and body detect and process touch and pain. The story so far shows the complexity and importance of the somatosensory system.

I wrote about a woman named 'G. That means she's lost all her sensors for mechanical touch. She can't read braille. If she puts her hands in her pockets, she can't tell a penny from a quarter. But remarkably, if you get her in the lab, you find that she has one form of sensation left: if you caress her forearm, or her leg, or another area of skin, she can tell roughly where it is, and she knows it's pleasant.
That's because she has retained a different, emotional touch system. It's mediated by special sensors called C tactile fibers , and it conveys information much more slowly. It's vague — in terms of where the touch is happening — but it sends information to a part of the brain called the posterior insula that is crucial for socially-bonding touch. This includes things like a hug from a friend, to the touch you got as a child from your mother, to sexual touch.
It's a completely different set of sensors and nerve fibers that wind up in a different part of your brain. And then, again, there's another system that just conveys the negative emotional aspect of the pain," Linden says. And there are also some rare cases — people called ' pain asymbolics ' — who lack the emotional pain system.
So they have the 'facts' of pain, they're aware of it, but it doesn't bother them. If you stick their hand in a bucket of ice water a standard way of inflicting pain in a lab , they know it hurts, but they don't actually mind it. They were barely touched during the day," Linden says. They had weakened immune systems, and skin ailments. We're not entirely sure why it happens, but it seems that early touch experience is extraordinarily important for development both cognitive function and a healthy body.
Initially, when isolators were first invented, people thought you should just leave them in there alone, so they don't get infected. But then they might not get touched for the first two months of life, which turns out to be disastrous.

Our sense of touch deteriorates as we get older. Suggest a correction. Using our senses—touching, tasting, seeing, hearing, and smelling—is how we first gather information about the world around us.
Our sense of touch is especially designed to gather information about our surroundings…as well as to connect with each other; the ability to touch helps to create bonds between us. Affectionate, positive touch is associated with enhanced learning, language processing, improved problem solving even physical growth in children.
Information from our sense of touch enters the nervous system from every single part of the body. There is a socio-emotional connection to the physical action of touch—it gives a socio-emotional context to the touch. Some of the first tactile experiences you offer your baby are cradling and hugging. Hugging impacts all developmental domains: physical, emotional, social and cognitive.
