I played around with doing this (for a brain coral).

Wouldn't do if the brain was the main component of the scene, but might be a
help if it's just a few of 'em in jars on a backshelf or something...

#include "functions.inc"

#declare F_1 = function(x,y,z){(pow(x,2)+pow(y,2)+pow(z,2)) +
f_ridged_mf(x*10,y*10,z*10,1,1,1,1,0,3)/5 - 2}
#declare Brain1 =
isosurface {
  function {F_1(x,y,z)}
  max_gradient 20
  contained_by {box {-5,5}}
  pigment { rgb<0.7,0.5,0.5> }
}
object{Brain1}
