This brain circuit may explain fluctuating sensations—and autism

[Робот]

Sometimes a gentle touch feels sharp and distinct, other times it fades into the background. This inconsistency isn’t just mood—it’s biology. Scientists found that the thalamus doesn’t just relay sensory signals—it fine-tunes how the brain responds to them, effectively changing what we feel. A hidden receptor in the cortex seems to prime neurons, making them more sensitive to touch.
