Fig. 6. Cell count totals in Sepia officinalis. Total number of cells labeled in the brain and stellate ganglion (SG; A) and the percent of labeled cells located in and outside of the posterior subesophageal mass (PSEM; B) from each of three dye-injected fin nerve branches (A1, P1, A1a) are shown. For branch P1, only cells in the brain were counted, as the SG was not sectioned; thus, cells outside of the PSEM are from the brachial lobe (BRL) only.
