Extended Data Fig. 2: SpikeyGi2 responses in vitro across neuronal cell types.
From: High-speed low-light in vivo two-photon voltage imaging of large neuronal populations
(a) Circuit diagram of recorded cell types in the anterior olfactory nucleus and main olfactory bulb. (b) Example of in vitro fluorescence in an anterior olfactory nucleus pyramidal neuron expressing SpikeyGi2 in response to 10 Hz and 50 Hz action potential trains. (c) Example of in vitro fluorescence in a main olfactory bulb periglomular neuron expressing SpikeyGi2 in response to10 Hz and 50 Hz action potential trains. Scale bar: 10 𝜇m. These experiments were performed 5 times with similar results.
