✦ Synopsis

Carnosine has been applied by microiontophoresis ot identified neurones in the olfactory bulb of the rat from solutions of different pH. Although mainly without effect when compared with conventional excitatory and inhibitory amino acids, the dipeptide tended to be depressive when ejected as a cation and excitant when ejected as an anion. The results obtained are not in favour of this substance being an excitatory transmitter in the primary olfactory pathway.
