- OpenWater’s holographic infrared “de-scattering” technique was highlighted as the most promising non-invasive BCI approach; it uses fast LCD phase modulators to make the brain effectively transparent and detects single-neuron firing via refractive-index changes in the lipid bilayer during action potentials.  
- Participants dismissed conventional EEG-based BCIs as having insufficient spatial resolution and signal-to-noise ratio for single-neuron work, and criticized OpenBCI’s $800 hardware as “just an ADC” with sparse documentation.  
- The group noted a recent shift in channel focus from neuroscience toward synthetic biology and genetic engineering, with only intermittent interest in BCI topics.  
- A new visitor researching non-invasive speech transcription for locked-in patients was directed to subvocal recognition and statistical mapping techniques, but warned that acquiring the hundreds of hours of labeled EEG data needed for deep-learning approaches would be prohibitive.  
- Links shared included Andrew Hessel’s “Catalyzing Coherence” podcast episode on synthesizing our genetic future, a Python integer-division history post, and Matt Blaze’s tweet arguing that politeness cannot fix fundamentally insecure software.
