"Rapid temporal processing in the olfactory bulb underlies concentration-invariant odor identification and signal decorrelation", Karadas et al. 2026 (Dima Rinberg's lab).
https://www.nature.com/articles/s41593-026-02250-yCircuits in the mouse olfactory bulb implement a rapid filter:
"Animals who rely on smell need to identify and discriminate odors despite fluctuations in concentration, yet odor receptor activation is strongly concentration dependent. [...] We found that the glomeruli [...] activated earliest in a sniff robustly represented odor identity across concentrations, ... . [via] a short temporal window of excitability at a sniff’s onset, followed by prolonged odor-evoked inhibition. The OB implements a rapid temporal filter, which is responsible for stabilizing identity across concentrations while decorrelating responses between odors."

Now diving into the processing and transformation of raw olfactory stimulation of sensory neurons to the output of the olfactory neuropils via projection neurons, see these two papers, one in fly and one in zebrafish. The former shows how PNs respond to the derivative of the input, which is essential for tracking stimuli up a gradient, and the latter shows how the LNs perform a whitening of the olfactory input (to decorrelate the inputs into the otherwise multiply stimulated olfactory receptors and their corresponding sensory neurons) which optimally prepares similar stimuli for separation:

And in flies in particular, all papers signed by Rachel Wilson as the senior author (now a professor at Harvard Medical School) in the early 2000s are absolutely outstanding, on probing with electrophysiology and genetics the various synapses in the fruit fly olfactory system, e.g., the sensory neuron (ORN or OSN, synonyms) to the projection neurons (PNs), or the local neurons (LNs), or the LNs to each other or to the PNs, and the PNs back to the LNs. She's written a couple of reviews on the subject that are very accessible for the curious student.
