The study of cortical oscillations has undergone a renaissance in recent years because of
their presumed role in cognitive function. Of particular interest are frequencies in the
gamma (30-100) and theta (3-12) range. In this paper, we use spike coding techniques
and whole-cell recording to assess the ability of individual pyramidal cells of the piriform
cortex to code inputs occurring in these frequencies. The results suggest that the spike
trains of individual neurons are much better at representing frequencies in the theta range
than those in the gamma range.
