Overview
The Axon-1N-1P family is a set of bidirectional neural probes designed for in-vitro and in-vivo applications featuring up to 512 titanium nitride (TiN) electrodes for recording and up to 16k gallium nitride (GaN) LEDs for optogenetic stimulation. Two Science ASICs provide the core functionality of the probe: the Nixel 512™, a full-bandwidth 256-channel differential ADC; and the Pixel 16k™, a 7-bit passive LED driver. Together, they enable closed-loop neural stimulation and recording for next generation neuroscience applications.
