I think my favorite piece of anatomy ever is the pes hippocampus. I remember seeing them in neuroanatomy dissection after carefully cutting through the temporal lobe and seeing these cute little toes.
I was getting rusty on my Maya modeling, so for now am skipping ZBrush to build at least the basics in here. Not all of the anatomy is there yet/size relationships are off for the time being, but here at least is the beginning of the mesencephalon and the hippocampus. I want to get the entire limbic system constructed; it’d be a good modeling/sculpting challenge! And potentially useful for future projects.
