Abstract: Physical expressions of affection play a foundational role in early brain development, but the neural correlates of affective touch processing in infancy remain unclear. We examined brain responses to gentle skin stroking, a type of tactile stimulus associated with affectionate touch, in young infants. Thirteen term-born infants aged 11-36days, recruited through the FinnBrain Birth Cohort Study, were included in the study. Soft brush strokes, which activate brain regions linked to somatosensory as well as soci… Show more

“…A sagittal 3D T1 sequence with 1.0 × 1.0 × 1.0 mm voxel size (TR 1,900 ms, TE 3.26 ms, TI 900 ms) was also acquired. Additionally, the imaging included field mapping, a set of DTI images and functional imaging for some participants (data not reported here) (19).…”

“…These kinds of social expectations might thus affect the way in which affective touch is perceived and enjoyed. Consistent with recent research suggesting that infants as old as two months old show selective sensitivity to affective touch 45,46 , we hypothesized that any difference in this discrimination in adulthood based on attachment styles would relate to topdown effects. Indeed, we also observed that insecure attachment style was related to the overall Attachment style and affective touch 22 perceived pleasantness of our tactile stimuli, irrespective of whether or not they were in the CToptimal range.…”

“…during the critical period for the development of IMW, show selective behavioural and physiological sensitivity to stroking touch at 'CT-optimal' velocities as compared to similar but 'non CT-optimal' velocities (< 1cm/s -1 and > 10cm/s -1 ) 44 . Indeed, the notion that the neural substrate for detecting pleasure associated with this kind of touch develops early has been supported by recent findings suggesting that gentle touch at CT-optimal speeds in newborns leads to increased BOLD activity in brain regions associated with the socio-affective processing of touch (i.e., postcentral gyrus 45 and insular cortex 45,46 ). A recent behavioural study further found that this type of touch helps infants tune to social signals, such as faces, more than other types of touch 47 .…”

“…This link is partially explained by sensitive and responsive parenting behaviours, as mothers tend to use different types of touch as a function of the type of cue communicated by the infant and as a result of the infant's temperament or disposition (Ferber et al, ). As argued, the study of emotional and motivational aspects of touch, which has been referred to as affective touch (see McGlone et al, ), has been emphasized in recent years (see Cascio et al, for a review) as well as the neurophysiological underpinnings of affective touch in early experience in humans (see for example Jönsson et al, ; Pirazzoli, Lloyd Fox, Braukmann, Johnson, & Gliga, ; Tuulari et al, ). However, despite this recent work, as stated, there is an overall failure of the attachment and maternal sensitivity literature to include the type of precise definition of touch present in other disciplines of science.…”
