| Abstract: | Summary In the brain of Ophryotrocha puerilis swollen nerve endings filled with electron-lucent vesicles and aggregates of vesicles were observed. The vesicles do not resemble elementary neurosecretory granules. Tests for biogenic amines were negative; no dense-core vesicles were found. The vesicle type described here cannot be related to any of the types thus far found in nerve cells.Supported by Deutsche Forschungsgemeinschaft Pf116/3 |
