Fig. 8From: The size of via holes influence the amplitude and selectivity of neural signals in Micro-ECoG arraysSpatial selectivity values calculated for neuron pairs located at different depths (500, 1000, and 1500 μm) and for different sizes of the via holes. The distance between Neuron A and B is either 707 μm (solid lines) or 2121 μm (dash lines) as shown in Fig. 2. In all cases, the signals were recorded at the contact that is aligned with Neuron ABack to article page
