When the fetus is just a few weeks old it starts to develop its brain. And soon after the baby starts to wiggle around in the uterus though the mother cannot yet feel it.

Electrical activity can be detected after a few months. However, this is not "brain activity" but rather activity from neurotransmitters. The brain is not yet fully formed.

I was not able to find out exactly when activity begins, but it begins to develop at week 5. I would assume function would begin immediately because that is when the heartbeat begins as well.
