Narrative:

During cruise at FL350 approximately 70 mi east of the sby VOR, operating from jfk to pbi, the first officer and I noticed smoke rising from the center console of aircraft in an amount about equal to a smoker's exhale. Within a few moments, the #1 flight attendant called the flight deck to say they could smell burning insulation, mostly in the forward cabin. No other smoke was noted, no equipment malfunctioned, no ECAM occurred and no circuit breakers were noted to have popped. We notified ZDC and sent an ACARS message to company operations of the problem. The smoke was gone from the flight deck prior to completion of the smoke checklist. The #1 flight attendant called again to say that the smell was gone from the cabin. I informed her that we were going to return to jfk and to advise me if there was any change in the cabin. We declared an emergency with ZDC. Maintenance control was contacted through a phone patch with commercial radio. We did get a landing gear control indicator unit 2 ECAM advisory while descending through 8000 ft approximately 30 mi from jfk. A visual approach was completed to runway 31R at jfk.
