Key Points
Tokyo [Japan], December 11 (ANI): Tokyo Metropolitan University researchers have studied how an infants brain reacts to touch based on the amount of oxygenated haemoglobin in their blood..
They discovered that while the amount of variation in levels over time changes with infant age, the moment at which they peak remains constant...
With NIRS, an array of external sensors placed on an infants head lets scientists track how the flow of different compounds in the brain changes over time..
As the brain responds to input from the outside world like light, heat, and touch, oxygen rushes to the brain; NIRS lets us pick out levels of haemoglobin, even telling apart whether it is carrying oxygen or has already delivered its cargo...
Looking at a range of infants aged zero to one, the team placed sensors on infants scalps as they slept, and tracked how oxygenated haemoglobin levels changed over time as their limbs were given a very gentle shake..
