BOSTON UNIVERSITY (red.), ‘MEMORY IS A BIG PART OF THE SENSE OF TOUCH’, https://www.futurity.org/senses-touch-memory-2680522/, Futurity (JANUARY 10TH, 2022)
When you touch something, whether stepping onto a sandy beach or stroking the back of a dog, sensations fly into your brain. You feel the coarse grain of the sand under your feet, the fluffiness of the fur on your hand. (…) But you also bring a bit of yourself into the feeling: Along with the external stimulation from the beach or pup, there’s the memory of past moments—toweling sand from your toes during a summer vacation, snuggling with a much-missed family pet. We all agree that something feels abrasive or soft, but interpret that sensation slightly differently. (…) The study may be significant for our understanding of a range of neurological disorders and neuropsychiatric diseases that can alter sensory perception, from strokes to autism spectrum disorder. Improved knowledge of the brain’s circuits (…) may pave the way for more targeted treatments and interventions.
