Changes in the properties of single receptors in the skin of the hand with healthy ageing

We know that the ability to detect contact with the skin changes with age. These changes might occur in the sensory receptors that lie in the skin, in the nerves that transmit sensory signals from the receptors to the brain, in the processing of sensory signals in the brain, or in the properties of the skin itself.

We have recorded signals from the sensory receptors before they reach the spinal cord in response to stimuli of different intensities in both young and old people. This will help determine why and where sensation deteriorates with age.
