Did you know?
How do we feel cold?Scientists have traced the roots of feeling cold by identifying a protein that plays a key role in sensing cold. Neuroscientists at the University of Southern California have visualised cold fibres, strands reaching from sensory neurons near the spinal cord to nerve endings in the skin tuned to sense different types of cold. Prior studies have suggested that cold-sensing neurons are specialised, with some detecting painful cold sensations and others detecting more pleasant ones.
