Tracking the unborn brain into childhood

[image error]A brain scanning technology called MEG is being used to track the function of unborn babies' brains as they grow inside the womb until after they've been born.

The full name for MEG is magnetoencephalography and it works by reading the magnetic fields created by the electrical signalling in the brain.

One of the advantages is that it can be used at various angles, doesn't require the person to be in a cramped space, and is less sensitive to movement, so is ideally suited to scanning babies.
