Decision making often relies on accumulating evidence for different choices. Traditional decision-making models predict that neural activity will exhibit persistent ramping with evidence. By contrast, recent studies in rodents and primates have observed that the representation of accumulated evidence shifts between different neural populations as decision-making demands change within a trial. Prior models only accumulate and maintain evidence, but fail to explain the transfer of graded evidence between populations. This transfer supports the continuous representation of a decision when an anim
