Explore the science behind how your body and brain process different sensations like touch, pain, temperature, and spatial awareness.
--
We don’t often think of touch as being a vital part of movement, but touch is one part of a network that oversees all the sensations arising from the surface and interior of our bodies. Touch, pain, temperature, and our spatial awareness are regulated by this system. So, how exactly do our brains process these sensations? And what happens when something goes wrong? Antonio Cataldo investigates.

I’ve had severe migraine before to the point that I needed to get my brain scanned because it resembled a stroke. One half of my body went numb and I had aphasia which means I couldn’t speak properly. It is rlly freaky to lose feeling. I can move my body but I have to look at it to confirm movement because I really couldn’t feel it move. And walking was a nightmare. People don’t know how much we depend on our sense of touch to walk in a balanced way. Depending on eyesight alone is really tough and downright impossible as someone with a migraine whose eyesight was also affected. I was not aware of how we walk because we just usually depend on our sense of touch.

Body and mind connection is fascinating. I'm a SA survivor and it's very interesting how trauma is stored in the body. I sometimes disassociate from my body, which is what I did to mentally survive the SA. Problem is it still happens now when I have flashbacks or am triggered by things. The book The Body Keeps the Score by expert Bessel van der Kolk discusses how yoga can retrain the brain and body to understand that it is safe now, to untrap it from the trauma of the past.

I had a mild stroke 9 years ago and for a couple of weeks I lost all feeling on the left side of my body. I could still move and walk but like the video describes, I had to watch my left hand to know what it was doing. If I picked something up, I didn't know how tightly I was gripping it so if I stopped watching it, I would drop things. Luckily my feeling came back. A man in my stroke recovery group never got his feeling back on one side and he accidentally burned his 'unfeeling' hand really badly on a grill. he didn't feel it but eventually noticed the smell of his burning hair and looked down.
