Summary
It has been demonstrated by cytophotometric measurements of the DNA-content in glial- and nerve cells of the snailsHelix pomatia (Stylommatophora) andPlanorbarius corneus (Basommatophora) that the giant nuclei of nerve cells in the central ganglia contain more than tens of thousands of DNA compared with sperm nuclei. According to the DNA-content of sperms (=n), the values for glial cells are between 2n and 4n for both species.
