Mesoscale Two-Photon Calcium Imaging of Population Level Odor Responses from the Mouse Olfactory Bulb

This study explores odor-evoked activity representation in the olfactory bulb (OB) and how odor responses enable odor discrimination. Contrary to some previously cited theories that suggest a sparse representation, we hypothesize a more dense representation during odor presentation. A key question is how odors are reliably encoded in OB activity patterns, and how these patterns contribute to...
