Collection route: [[collections/Neurotech|Neurotech]]. - **INF-0037 — Strongly indicated.** Voltage indicators read the electrical event directly rather than its calcium shadow, trading signal-to-noise for temporal fidelity. As indicator brightness improves, optical readout crosses into spike-timing resolution and becomes a genuine alternative to electrodes at scale. <!-- END RESEARCH INFERENCES 2026-09-11 -->
