Avinash Singh, a BCI researcher at the University of Technology Sydney, said NEO has a 'relatively less invasive' design than Neuralink’s N1 chip because its sensors sit on the dura mater rather than penetrating the brain cortex.

Singh stated that NEO’s design presents a lower risk of hemorrhage, glial scarring, and long-term signal degradation, resulting in fewer regulatory constraints.
