Fig. 1From: The size of via holes influence the amplitude and selectivity of neural signals in Micro-ECoG arraysFinite element model of a rat brain cortex containing a μECoG electrode array positioned on the pia mater. A: A small box (5x5x2.5 mm) with extremely fine mesh is defined inside a larger one (10x10x6.1 mm). B: Detailed mesh view around a metal contact (100 μm, orange circle) and a via hole (200 μm, white circle) is shownBack to article page
