Simultaneous Neural Recording Active Pixel Sensor Technology
Plexon Inc and Corticale have partnered to offer SiNAPS , an implantable active pixel sensor CMOS-probe for simultaneous large-scale neural recordings. These small-area, ultra low-power active implantable devices enable high-resolution brain activity recordings with the highest electrode array density and minimal wiring available on the market.
SiNAPS probes are high-channel count, active electrodes, similar to other silicon active probes available and popular today (E.g., NeuroPixels). However, what makes SiNAPS probes unique is the ability to record from all the electrode sites, not only a subset. This means a user can record from all 256 channels of a 256 channel SiNAPS probe. Same for the 512 channel and 1,024 channel versions.
SiNAPS probes are available now to Plexon OmniPlex users for beta testing. In January 2022, more probe designs will be available for more users. To start, the probes will be available and supported in a 256 channel configuration. Probes with 512 sites and 1,024 sites will be available and supported soon.
SiNAPS probes require an OmniPlex data acquisition system from Plexon. Please contact your salesperson at Plexon for more information or reach out via firstname.lastname@example.org.
Modular circuit architecture: Versatile modular architecture enabling tailored and rapid solutions for any customer and application
Versatile fabrication flow: low-cost prototyping of CMOS-probes
Compact and scalable devices: Incredibly compact electrode-pixels with local front-ends enable the realization of arrays with the highest electrode density available on the market and scalable numbers of simultaneously recording electrodes
Discuss your needs with a Plexon Sales Engineer to determine the best configuration for your upcoming experiments. It may also be possible to produce arrays beyond the specifications outlined in the Technical Specifications tab.
SiNAPS probes are customizable, as can be seen from the table below. It may also be possible to produce arrays beyond the specifications below. As a result, it is recommended that you discuss your needs with a Plexon Sales Engineer to determine the best configuration and if your unique request can be accommodated.
