I know The Body Of Fornix first start in both Hipoocampi and comes out the back. Then goes up to For the body of the Fornix. But inbetween the 2 Fibre right befor it gets to the Body of Fornix it has Hippocampal Commissure between them connecting them. I do not understand what it is I thought it just connected the two Fibre befor the come togather to form the Body of Fornix. Then I thought it had something to do with the Corpus Calossum. But I just get more mixed up?
