Gamma oscillation peak in ΔF/F, corresponding to the average voltage change if a conversion factor of −0.47%/mV (Kuhn et al., 2004) is applied, and the voltage change under the assumption that only dendrites participate and that 23% of the membrane surface is contributed by dendrites (Braitenberg and Schüz, 1998)
