Odor identity decoding by mitral/tufted cells in the olfactory bulb from large-scale pooled datasets The mechanisms by which the olfactory bulb encodes odor information are fundamental to our understanding of sensory processing in the brain. Here, we analyze large-scale pooled electrophysiological recordings and respiratory data from awake mice to ...

Not relying on firing rate alone, odor identity is encoded through firing patterns that align with respiration. Decoding accuracy improves as more neurons are sampled and activity is integrated across respiratory cycles. #Olfaction
