Voltage profiles for off-center positioning of the neuron. Top panel: 2D versions of the voltage fields for different sizes of the via holes; Bottom Panel: Voltage profiles recorded from neurons at three different depths (500 μm, 1000 μm, and 1500 μm) and via-hole sizes, at the bottom surface of the electrode array (4 × 4 mm) along the diagonal axis that goes through the centers of the holes and contacts (see Fig. 2). The heat maps for the corresponding neuron depths are shown as insets on the right. 0 mm is the array center
