Triangle Biosystems International offers a family of channel multiplexing analog headstage sub-assemblies designed to significantly reduce tether density and increase interface efficiency between implanted electrodes and external neural recording/analysis equipment. Each headstage preconditions as many as 32       neural signals into a single multiplexed output, providing a high gain, bandpass filtered buffered connection.

 

The M-Series haadstage design is based on a custom,low power VLSI developed by TBSI. The result is a data acquistion solution with superior performance and reduced wire connection in a very small form-factor with less weight. The complete recording system includes a demultiplexer unit with system gain of 800 (customizable upon request). Use of a slip-ring commutator is highly recommended to capitalize on these low wire counts to further improve in vivo mobility and behavior. Our multiplexing hardware is ready for integration with our ADC hardware and NeuroWare® data acquisition software.
