Simultaneous recordings were taken from two widely separated branches of the olfactory nerve of the frog. Odors from a variety of chemical substances were blown into the nares, and each elicited a different response magnitude ratio between the two branches. In addition, the time lapse between the two nerve responses differed for different chemicals. This suggests a time-space encoding of the mucosal response to odors.
