Overview

Two EEG experiments reveal how evidence accumulation occurs across processing levels, suggesting the integration of perceptual information is more complex than previously thought.

Key Points

Participants utilized two pulses of motion evidence, but the second pulse was underutilized despite no decrease in accuracy with longer gaps.
Motor beta lateralisation tracked cumulative evidence across pulses, maintaining the decision variable until a response was made.
Centroparietal positivity indicates evidence accumulation, peaking with each pulse's information, then returning to baseline between pulses.
A model describes how information integrates transiently at the CPP level and is sustained at the motor level until a bound is reached.
