Active High Channel Count Probes: SiNAPS



NeuroNexus has partnered with Corticale to help make this advanced probe technology available to researchers around the world. SiNAPS products utilize a new probe technology with active CMOS circuitry integrated onto the probe. SiNAPS technology is an innovative advancement in multi-electrode solutions for in vivo electrophysiological studies on central and peripheral nervous system. This technology implements the Active Pixel Sensor (APS) concept in which active circuits for signal amplification, low-pass filtering, and multiplexing read-out are located directly underneath each electrode-pixel. To access NeuroNexus' existing design catalog for 64-, 128- and 256-channel Activus probes, check out Activus-NNx.
