Fig. 2From: The size of via holes influence the amplitude and selectivity of neural signals in Micro-ECoG arraysArrangement of the 8 × 8 contacts (filled circles) and the via holes (open circles) in the array. The center-to-center distance between the via holes and the contacts is 500 μm in the horizontal and vertical directions. For selectivity analysis, the off-center neurons, Neuron A and B, are either aligned with the contacts that are 2121 μm apart as shown with crosses, or with the contacts on each side of the central hole that are 707 μm apart. The via hole in blue is at the array centerBack to article page
