This study will attempt to measure the direct effect of pleasant skin touch on the developing infant brain. The massage intervention stimulates a specific class of unmyelinated C-fibres in the skin called C-touch (CT) afferents, and effects will be assessed by monitoring brain responses (GentleTouch Project) in a prospective cohort study.

This is a single-centre proof of concept translational study to determine how and when Somato-sensory evoked potentials develop over the first 4 months of life.

The aim of this study is to explore if the investigators can measure the cortical response from the scalp of infants using standard non-invasive EEG techniques, due to the activation of CT afferents and explore how the cortical response changes in regard to age. Preform a longitudinal study on 40 subjects at approximately 4 weeks and 4 months of age. The Gentle Touch study will examine the effect of gentle positive stimuli applied to an infant's forearm on cortical responses at two time points within the first 4 months of life.
