Meeting Abstract 34.1  Friday, Jan. 4  Neural development in the polychaete annelid Capitella sp. I SEAVER, Elaine C.*; MEYER, Neva P.; University of Hawaii; University of Hawaii seaver@hawaii.edu A key step during early central nervous system development is fate specification of neural precursor cells, which generate the entire brain and nerve cord. To date, the basic mechanisms […]
