There are 512 electrodes and 529 LEDs on this probe. The electrodes are patterned in a 23 x 23 square grid with no electrodes in the corners and a pitch of 150 μm. The LEDs are arranged in a 23 x 23 square grid with a pitch of 150 µm. The two grids are staggered, so the electrode-LED pitch is 75 μm. The total active portion of the cell culture well measures 3.56 x 3.65 mm2. There are 4 reference electrodes, all shorted together, at the corners of the array to provide a spatially-average reference signal for single-ended measurements.
The probe consists of two pieces: an FR4 PCB containing control and power electronics; and a microfabricated sapphire substrate housing the stimulation and recording ASICs, as well as the cell culture area.
Hardware Requirements
To get started using an Axon-1N-1P Probe, you will need:
- A SciFi wireless headstage.
- USB Type-C® data cable (USB 3 2x2 required, 10 Gbps, USB 3.2, 2x2 on the packaging are good indicators).
- A WiFi network
- The network must be capable of WiFi 5 (802.11ac) or later versions. To get best performance, use WiFi 6 (802.11ax 160MHz).
- A PC running the synapsectl command line tool.
