Topic: choice memory

A computation that is thought to underlie many decisions is the gradual accumulation of noisy evidence over time until a bound is reached, which triggers the commitment to a choice. The integration-to-bound framework captures the behavior in many decisions, as well as the pooled responses across neurons in many brain regions, suggesting that choices are formed based on the accumulated evidence encoded in neuronal firing rates. However, the correspondence between accumulated evidence and neuronal dynamics is only on aggregate. The choice-related dynamics of individual neurons are heterogeneous
