They used two brains in the Alien Autopsy movie by Warner Brothers, neither of which had the soft jelly-like consistency or the two tone (blood black, and fat white) colouring of the 'original'.  Rather they were hard.  The first human-like and red, the second haggis-like and grey.

Here also are the recent shots of the 'debris', but they have had 11 years to make it.
