| description | The hypothesis that odor-specific patterns of mitral cell activity during odor discrimination might be found in the corresponding spatial patterns of electroencephalogram (EEG) amplitude over a surgically accessible segment of the bulbar surface was tested in rabbits with chronically implanted electrode arrays. The spatial spectrum of the bulbar EEG was derived and compared with the spectrum predicted for the granule cell generator. Spatial filters were devised to identify, enhance, or remove the granule cell contribution to the EEG. Spatial deconvolution was applied to the filtered granule cell activity patterns to correct for distortion caused by volume conduction. The results indicated that the bulb generated odor-specific spatial patterns in rabbits trained to discriminate between two odors. The odor-specific information was not localizable to subsets of channels. This suggested that the discriminative output of the bulb involved the entire structure, even though the receptor input was delivered to limited subsets of mitral cells. |
