Re:Section through an octopus shows the mouth passing through the brain

Based on what appears to be pattern in the "top brain" I believe it to be some kind of secretion or filtering organ. Based on my reference links above in the reply to bluenose69, I think it is the digestive gland. The stomach is actually much smaller and has a hollow opening at the very "top" of the octopus.

First, I am open to correction. I usually focus on human anatomy, but have a special place in my heart for histology. This image is a histological slide, (a picture of stained cells) and rather low resolution, so specific cell structures are difficult to determine. Based on my education, experience, and links below, I believe the following to be the labeled anatomy.
