Premature baby brains can’t tell pain from touch – New Scientist

Premature babies up to the age of 35 weeks had bursts of activity across the whole brain in response to both pain and touch, but a change happened around 35 weeks. Between 35 to 37 weeks – just before a fetus would normally be born – the brain seemed to become able to tell the two stimuli apart. The responses to both pain and touch now took place in specific areas on the front, back and sides of the brain, but the signal was much stronger for pain.
