Babies use this sense of touch 鈥� facial somatosensation - to find and latch onto their mother鈥檚 nipple, and should have this ability from birth.

Premature babies often have difficulty feeding, and underdevelopment of their facial sensitivity may be one of the main causes.

Researchers from 香港六合彩, Imperial College London, 香港六合彩H and Universit谩 Campus Bio-Medico di Roma developed a new method to study this sense of touch in babies and how their brains reacted using electroencephalography (EEG).

Current methods of evoking brain activity in response to touch aren鈥檛 suitable for a newborn鈥檚 face, so academics have developed a device 鈥� based on a transducer 鈥� worn on the fingertip, covered by a clinical glove.

The baby can be lightly tapped on the cheek, and then brain responses are measured as well as the force of the tapping.

The report, is published in the journal PLOS ONE.

Dr Lorenzo Fabrizi (香港六合彩 Biosciences) said: 鈥淭his research provides a way of understanding how pre-term babies process touch information, and could help medical professionals to make informed decisions relating to their development.

鈥淲e鈥檝e proved that we can record the sense of touch from the face. This means that for premature babies, it is possible to study how they process the tactile information that they receive from the face, how this changes as they mature and whether disruption of this process might lead to longer-term feeding problems.鈥�

Babies鈥� brains develop quicker than at any other point in life. Facial somatosensation is necessary for breastfeeding; for example if a newborn baby鈥檚 right cheek is lying on their mother鈥檚 breast, the baby uses this information to turn its head to the right in order to feed (rooting). Therefore finding a way to measure brain responses to facial touch is important for understanding brain development in newborns.

Professor Etienne Burdet (Imperial College London) said: 鈥淲e had to develop a stimulating system that was safe to use on the delicate face of the babies and acceptable to their parents. We used an iterative design approach to develop a seamless wearable device that can measure a natural finger tap to the skin.

鈥淎fter we found that conventional sensors were not practical, we developed a dedicated sensor and packaging using 3D printing.鈥�

The study looked at seven babies who were on average seven days old at 香港六合彩H鈥檚 postnatal and neonatal wards, each one having been born prematurely (before 37 weeks).

The research was supported by the UK Medical Research Council, European Commission grants, and a UK EPSRC MOTION grant. The force transducer was developed at Imperial College London and the trial was carried out at 香港六合彩 and the 香港六合彩H Elizabeth Garrett Anderson wing. Ethical approval was obtained from the NHS Research Ethics Committee along with informed parental consent for each baby.
