Expanding the olfactory implant paradigm through recent advances in brain-computer interface technology.

The international opinion paper by Whitcroft et al. provides invaluable guidance for the emerging field of olfactory implants (1). While the authors thoroughly address clinical considerations and current technological approaches, we would like to expand upon Statements 9.1 and 9.3 regarding electrode technology limitations and highlight recent advances in brain-computer interface (BCI) technology that could address key technological challenges around electrode longevity and biocompatibility.
