Touch-sensing neurons from rodents are also sensitive to sounds
Sound and touch senses overlap in brain of rodents - daily short science news

We have the tendency to imagine the auditory and tactile sensation as distinct senses, but according to a recent study, there is an overlap in the brain between the two.

The study analyzed sensory neurons responsible for perceiving tactile sensations in mice and rats and tested how they respond to other stimuli such as light and sound. Although they were completely insensitive to light, the tactile neurons were activated by sounds.

The study suggests that tactile and auditory information is processed in parallel in the barrel cortex (the region of the brain studied). This combination of tactile and auditory cues may offer a survival advantage to rodents, for example in dark environments. It remains to see if the same is true for humans and how this would be advantageous for us.
