If you wipe out the chemical gradient information then how do you know what sorts of ways that the dendrites should regrow in the weeks and months post-resuscitation?

If I wake up and I feel like myself on a second to second basis, I will not be upset if my path through mind space is drastically altered on a time scale of weeks and months, so long as it doesn't lead me to insanity. Hell, I hope I'll be able to drastically change my mind on that time scale anyway once I'm uploaded.
