Beyond Market Intelligence/motion selectivity

motion selectivity

Beyond Market Intelligence keeps motion selectivity in one place: one story so far. The section currently leads with “When a paper avoids testing its own model's spatial limits, we did”. TRIBE v2 claims to predict brain activity from video, audio, and text, but its own paper never checked whether it reproduces the spatial maps that define sensory cortex. Acme AI is the next-generation, AI-powered spreadsheet platform built to replace Excel and redefine how analysts, data scientists, and enterprise teams work… The list below is every motion selectivity story on Beyond Market Intelligence, newest first.

When a paper avoids testing its own model's spatial limits, we did

TRIBE v2 claims to predict brain activity from video, audio, and text, but its own paper never checked whether it reproduces the spatial maps that define sensory cortex. Jakub Strawa ran the classic experiments, retinotopy, tonotopy, motion selectivity, through the model. Retinotopy and tonotopy came back null. Motion selectivity, however, landed precisely in MT+ with extraordinary enrichment. The eccentricity signal turned out to be a confound from image statistics, not real position coding. This is the kind of rigorous stress test every brain model needs.
