Fig. 4From: The size of via holes influence the amplitude and selectivity of neural signals in Micro-ECoG arraysVoltage profile along the diagonal axis beneath the electrode array for varying substrate sizes as well as in the absence of a substrate. The recorded voltage increases with array size. The neuron is at a depth of 1000 μm from the pia surface and aligned with the center of the array. No via holesBack to article page
