The paramedial neurosecretory cells of the suboesophageal ganglion of the cricket, Teleogryllus commodus (walk.).
Ovariectomy, performed immediately after the final hatch, caused a reduction of stainable (neurosecretory?) MATERIAL IN THE PARAMEDIAL NEUROSECREtory cells (PNC) (A-type) of the suboesophageal ganglion in 10 day-old females of Teleogryllus commodus (Walk.). A concomitant increase in nuclear volume and in the incorporation of 35S-cysteine indicates increased synthesis of neurosecretory material. From these findings it is concluded that more stainable material is secreted in the cerebral neurohaemal organ after ovariectomy. A functional relationship between the PNC and the ovaries is suggested.
