That's the light purple region here. We have the mid brain, that's the center green region. And we have the hind brain, that's the lower portion that is shown in dark purple. Now, the forebrain and the high brain can be broken down into two subdivisions. In the case of the forebrain, we have our Teleencephalon and Dyncephalon regions. For the hive brain, we have the metincephalon and the myelincephalon.
