Information for decision-making and stimulus identification is multiplexed in sensory cortex

Nat Neurosci. 2013 Aug;16(8):991-3. doi: 10.1038/nn.3432. Epub 2013 Jun 23.


In recordings from anterior piriform cortex in awake behaving mice, we found that neuronal firing early in the olfactory pathway simultaneously conveyed fundamentally different information: odor value (is the odor rewarded?) and identity (what is the smell?). Thus, this sensory system performs early multiplexing of information reflecting stimulus-specific characteristics with that used for decision-making.
