# The Signal Constellation: compare fast brain rhythms with real-world performance

Exploratory EEG and optical-imaging research · No ready-made impairment detector. Imagine an accessible research dashboard displaying EEG timing, task performance, and carefully interpreted optical-imaging measures as separate layers of a cannabis study. Philippine and US teams could investigate whether a proposed signal remains reliable across sites, devices, and participant groups. Its most valuable use may be detecting where a confident theory breaks down, rather than finding a glamorous signature of genius.

## Chapter notes

Imagine an accessible research dashboard displaying EEG timing, task performance, and carefully interpreted optical-imaging measures as separate layers of a cannabis study. Philippine and US teams could investigate whether a proposed signal remains reliable across sites, devices, and participant groups. Its most valuable use may be detecting where a confident theory breaks down, rather than finding a glamorous signature of genius.

Published controlled research has investigated THC-related changes in EEG oscillations, while optical-imaging studies have examined intoxication-associated signals. These findings do not establish a universally accurate individual impairment test. Brain rhythms are not an intelligence score or a spiritual ranking; blood-flow-related signals are not direct recordings of thought.

Prespecify analysis, evaluate false positives and false negatives, and test generalization on independent data. Obtain separate consent for recordings and reuse. Keep exploratory cannabis signals out of employment screening, criminal judgments, parole decisions, and consumer diagnostic claims. If a tool ever moves toward clinical use, it needs its own validation and applicable device review rather than borrowing credibility from a research visualization.
