if you have taken my demo file (which it looks like) the noise is not moving, the sphere is moving through a 3d noise… you can see at the end as the sphere exits the layers the noise appears to be still (which it is) but until then the sphere is presenting and ever changing (because it’s moving) surface to the noise so the noise ‘moves’ on the surface
There are controls in the noise for movement but they are all zero (Movement and Speed) and there is an a animation control (Time Scale) in the Distorter but that is at zero too.
Here’s an example with the same settings (though I did change the Projection of the textures to UVW) but with gaps in the layers to better show the noise isn’t moving

But if you are going to move the sphere through the layers and not actually see the layers why not just use one cube that encompasses the same volume?
Custom textures would be possible but you would need a different picture for each slice/layer) or you would have to have a head model with complete internal structure
