Dendritic non-linearity and stability analysis procedure.

(A) Single-cell diagram. A pyramidal neuron receives input I and integrates it through a function g_dend. (B) Diagram of g_dend as a function of the input I (see Methods). α₁ controls the linear gain of the dendritic compartment; α₂ controls the amplitude of the non-linear term related to dendritic spikes; and I₀ controls the minimum input to elicit dendritic spikes. (C) Place field stability analysis. For each measurement of place field stability (see Methods) we perform the following steps: (i) we simulate one lap of exploration, without plasticity; (ii) we measure the place field of the postsynaptic neuron; (iii) we rescale this place field such that its peak is set to 1; (iv) we change the state of the network by adding noise to it; (v-vi) we repeat (ii)-(iii); (vii) we calculate the absolute distance between the two rescaled receptive fields.
