Rhythmic stimulation elicits multiple, concurrent neural responses

What the source reports

Reports that rhythmic light elicits several concurrent neural responses that shape perception separably, rather than a single entrainment response. This complicates the common reading of flicker studies as driving one oscillation.

Limitations

A laboratory visual-stimulation study, not an architectural one. Nothing here supports a claim about lighting in buildings.

NEURODESIGN reading

Useful to the practice as a brake. The 40 Hz literature is the clearest current example of a neuroscience finding being sold as a lighting specification several inferential steps before the evidence supports it.

Design questions and applications

None that can be stated. This is a reason to withhold a claim, not to make one.
