Where is my mind Nervous system regionalization in the acoel Hofstenia miamia
Meeting Abstract 50-6 Friday, Jan. 5 11:30 – 11:45 Where is my mind: Nervous system regionalization in the acoel Hofstenia miamia HULETT, R.E.*; SRIVASTAVA, M.; Harvard University; Harvard University rhulett@g.harvard.edu Bilaterians with clear anterior-posterior (AP) and dorsal-ventral (DV) axes represent a major transition in early animal evolution. Most bilaterian lineages show a restriction of the central nervous […]
