From: A biopotential optrode array: operation principles and simulations

Simulated temporal performance of the optrode at a single channel. Comparison of temporal changes in extracellular potential probed at the neuron (V e ), electric field across the liquid crystal (LC) layer (E z ), and electric polarisation of the LC (P Gz ) in the direction perpendicular to the optrode’s circular surface, measured directly below the neuron probe point.
