Abstract
On the basis of data from the literature and our own investigations I should like to sum up some properties of the neurons of Anodonta cygnea:
-
1.
Falck’s method (Falck 1962) gives green fluorescence in the majority of axons and in several nerve cells, and this, as made evident by analyses, originates predominantly from dopamine (Dahl et al. 1962, 1966; Zs.-Nagy 1967a). The dopamine can be depleted from the axons with reserpine. Three to four hours after reserpine treatment, practically no green fluorescence remains in the neuropile of the cerebral ganglion. Within 12 h, all cells produce green fluorescence in the cerebral ganglia, which intensifies for 2–3 days; from the second day, more and more green fluorescence is found in the axons as well (Zs.-Nagy 1967a).
-
2.
The second property of the neurons is that the majority of axons and several cells give a specific positivity with Sterba’s pseudoisocyanine fluorescence method (Sterba 1961) (Zs.-Nagy 1965). This method, according to Sterba (1964), indicates the carrier protein of the elementary neurosecretory granules.
