Paper

Brunton BW, Botvinick MM, Brody CD. Rats and humans can optimally accumulate evidence for decision-making. Science, 2013, 340(6128):95-98.

Notes

Foundational paper for the Poisson clicks evidence-accumulation task in rats. The Brody Lab archive used by the auditory_clicks vertical slice contains rat sessions collected over 2009-2024 in this lineage; per-rat psychometric findings here are extracted from the harmonized trials table for the five rats currently included in the local batch (A080, B075, B127, T014, T074).
