Abstract

1. The serotonergic system in the brain of the blowfly, Calliphora erythrocephala, was analysed by two different methods.

2. Serotonergic neurones were visualized by immunocytochemistry with an antibody against serotonin.

3. Putative serotonin receptors were localized by quantitative autoradiography of [3H]serotonin binding.

4. We found regions with a colocalization of immunoreactive neurones and binding sites, and regions with a mismatch as well.

5. In regions of overlap, which include the optic lobes and the central body complex, serotonin might act as a neurotransmitter.

6. In areas of mismatch, as found e.g. in the lateral parts of the protocerebrum, serotonin might have a modulatory action.
