Abstract(summary):
This paper presents a novel method for inferring the odor based on neural activities observed from rats main olfactory bulbs. Multichannel extracellular single unit recordings were done by micro-wire electrodes (tungsten, 50 ¹m, 32 channels) implanted in the mitral/tufted cell layers of the main olfactory bulb of anesthetized rats to obtain neural responses to various odors. Neural response as a key feature was measured by substraction of neural firing rate before stimulus from after. For odor inference, we have developed a decoding method based on the maximum likelihood (ML) estimation. The results have shown that the average decoding accuracy is about 100.0%, 96.0%, 84.0%, and 100.0% with four rats, respectively.
