Fig. 1: Strategies for using a single wire to serve many recording sites in switchable silicon probes.
From: Electrode pooling can boost the yield of extracellular recordings with switchable silicon probes
a Time-division multiplexing. Rapidly cycling the selector switch allows a single wire to carry signals from many recording sites interleaved in time. Triangles represent anti-aliasing filters. b Static switching. A single wire connects to one of many possible recording sites through a selector switch. c Electrode pooling. Many recording sites are connected to a single wire through multiple controllable switches.
