Reply #17: I'm at a bit of a loss here

For a moment I thought you might have some sort of point; then I read the full sentence from which you had bizarrely excerpted that bit:

"Infants born at 28 to 35 weeks of development showed comparable...
... brain activity."

There is no period after the word "activity" in the passage you quoted from.

Let's look at the whole thing, with my emphasis:

Infants born at 28 to 35 weeks of development showed comparable brain activity for the touch and heel prick, but infants born at more than 35 weeks of gestation exhibited a greater response to the heel prick than the touch.

What's not to get here?

The entire point is that up to 35 weeks, the infants show comparable brain activity in response to very different things. (That is, the brain activity is comparable as between stimuli, not as between infants of different ages.)

The brain activity in response to a non-painful touch is comparable to the brain activity in response to a painful prick.

Only at 35 weeks do the infants react more strongly to the painful than to the non-painful stimulus.

You are the one who has completely reversed the meaning. How, when the meaning is so clear? Why?
