Advice for a brain model

I want to make a model of a brain and I have already made the main parts but I still need to make the Cerebellum. It has a specific texture of a muscle and I can’t recreate that in blender so here is my base model

and here is how it should look like its bellow the temporal lobe. My model isn’t supposed to be 100 percent correct to the real world it just needs to be good enough but I would still like if the cerebellum would have looked like that on the picture. So is there a way to make that texture in blender?
