When the activity can be actively measured. Terry Schiavo, for example, stopped being a person when her brain stopped.

You can measure electromagnetic activity in an unfertilized egg. The question is when does this activity become brainwave activity.
We have ways of measuring brainwaves, it's not a mystery.
I never implied that we didn't. I'm telling you that we can always measure something and asking you to clarify which of these measurements constitute brainwave activity. Is the activity in the ovum a brainwave? Is it after the first signs of a notochord? After the notochord disappears completely? First cell to differentiate to eventually become part of the neural tube? When the neural tube starts bulging out? When there's enough bulging to see three district vesicles? Or five? Appearance of the first neuron? Or when neurogenesis stops? Or when the nervous system is sufficiently developed to take control of certain bodily functions? Or the activity when the nervous system is "fully developed" as an adult? Or something else?
