Summary The amount of neurosecretory material was measured in the brains of bees which had been used in a previous study (Vogel et al., 1977) for a determination of the rate of protein synthesis in the pars intercerebralis (PI). The brains of bees trained to short feeding periods contain significantly lower amounts of neurosecretory material than those of bees flying the whole day. The amount of stored material appears to decrease as the reinforcement of training is extended. The daily changes in the storage of secretory material in the PI and corpora cardiaca (CC) show no direct correlation with flying activity, either in trained or in untrained bees. Combining the data on protein synthesis with that on amounts of secretory material in the PI and CC, and taking into account the axonal flow conditions from the PI to the CC, the release of the Pi-material is estimated. These release curves correspond to the temporal activity pattern in all experimental groups.
