Does the fact that many non-human animals have pituitary disprove Cartesian Dualism?

IDK if the things listed are reasons it's problematic.  If damage to specific structures causes these issues, then it's safe to say that such structures are indeed required..and required to be intact and functioning, in order to feel what we call pain.

the fact that brain damage leads to loss of specific aspects of the conscious perception shows conscious perception arises out of circuits in the brain damaged.    the problem is it is difficult to map specific losses to specific damage.    

so when we see a structure in a different animal seemingly analogous to parts of human brain responsible for consciousness, we can’t use analogy to infer the extent of the consciousness.    so the fact that another animal appears to have a structure in the brain analogous to areas the support consciousness in humans, it certainly does not prove or even strongly indicate that animal is conscious of the same things as we humans, such as pain, or even their visual environment.

if there is even hint of some capability analogous to consciousness in humans then the consciousness must be quite like ours is anthropomorphic projection.
