Illustration of exploration volume and significant volume in various 3D electrode arrays. (A) Illustration of the concept of exploration volume and significant volume with a simple cubic electrode array. For better illustration, the electrode array in 3D is projected to 2D. Black dots indicate electrodes, and black squares indicate electrodes, with their sensing radius of signals, i.e. 75 μm, in light blue. Union of light blue area and darker blue is defined as exploration volume. Intersection area with at least from 4 depicted in dark blue, which is defined as significant volume. Exporation volume increases while the electrode pitch increases, i.e. 45 μm to 100 μm. But significant volume decreases while the electrode pitch increases, i.e. 100 μm to 45 μm.

Article Snippet: Although 3D silicon probes by stacking 2D probes have been developed[ – ] and commercialized (Neuronexus, ATLAS Neuroengineering), they cause severe tissue damage and are difficult to insert into the brain and therefore unfortunately are limited in their usage in larger brain regions.

Techniques:

Simulated distribution of 1000 neurons network in a barrel column with 6 layers. (A) and 384-channel 2D linear electrode array (B1) and 384-channel 3D simple cubic electrode arrays (B2). (C) Increase the noise level by injecting white noise. From top to lower, signal-to-noise ratio of 1, 2, 5, 10, 20, 40, and non-injected raw data.
