Assessing within‐trial and across‐trial neural variability in macaque frontal eye fields and their relation to behaviour

The conventional approach to understanding neural responses underlying complex computations is to study across‐trial averages of repeatedly performed computations from single neurons. When neurons perform complex computations, such as processing stimulus‐related information or movement planning, it has been repeatedly shown, through measures such as the Fano factor (FF), that neural variability across trials decreases. However, multiple neurons...
