And what a nice photo. Could only have been done by Miquel Vila-Farré – thanks for acknowledging so in the caption. Miquel, my colleague during PhD times in Barcelona. Great memories of many adventures in planaria-land.
I still keep in the back of my mind Pentacoelum hispaniensis, a tiny planarian that one day I'd like to image with FIBSEM to then map its complete nervous system. Would make a great model for how a brain repairs itself.
If interested to do a postdoc on this, I'm game. Write to me.
