It may have to do with your Brain Sphere being solid glass, not a "bubble".
I rendered the attachment with the following code.
#declare A=text{ttf "crystal.ttf","A",.1, 0 pigment{color green 1}
translate<-.25,0,0> scale 3}
sphere{<-3,2,0>,2 pigment{rgbf <1,1,1,1>} interior{ior 1.33} finish{phong 1}}
object{A translate <-3,1,0>}
difference{sphere{<3,2,0>,2}
sphere{<3,2,0>,1.9}
pigment{rgbf <1,1,1,1>} interior{ior 1.33} finish{phong 1 reflection .1}
}
object{A translate <3,1,0>}
The left is a solid glass sphere, and the right is a hollowed out sphere
(difference).
give it a try
