Primary cultures derived from embryonic mouse brain and spinal cord were exposed to /sup 125/I-labelled tetanus toxin and subjected to autoradioraphy. Cells with neuronal, but not glial, morphology selectively accumulated the toxin. The distribution of the grains over these cells and their processes was not uniform, discrete processes showing heavier labelling.
