In vivo measurements of odorant responses in the mouse olfactory bulb using the GEVI ArcLight and two GCaMPs. Left panels (A,C) comparing ArcLight and GCaMP3 signals from opposite olfactory bulbs in the same preparation in response to odorant presentations lasting one and two breaths. Right panels (B,D) comparing ArcLight and GCaMP6f in response to odorant presentations lasting one and two breaths. The ArcLight signals are substantially faster than those of the GCaMPs.
