Summary

The work describes electrical and thermal changes in the olfactory bulb of hibernating hedgehogs (Erinaceus europaeus) during active movement, in the waking state, and in hibernation. Histochemical determinations of RNA, glycogen, and phosphomonoesterase were made for a parallel study of the metabolic activity of the cells of the bulb. It was shown that there was at first no change and later an accumulation of these substances, and at the same time electrical activity in the bulb was first reduced and then finally disappeared. The metabolic changes were most active in the first stage of the neuronal circuit of the bulb, i.e., in the mitral cell with its recurrent collateral, and in the short-axoned internuncial neurone.

We have proposed a possible function for this circuit in the establishment of the electrical rhythm of the olfactory bulb.
