The paper investigates how temporal weighting of sensory evidence in decision-making is shaped by interactions between sensory and decision circuits using behavioral, neural, and computational models in macaques.

The paper shows that prefrontal cortex neurons during working memory tasks form structured subpopulations rather than random mixed selectivity, with distinct activity profiles for visual stimulation and memory maintenance.

This study uses computational models to show that age-related myelin dystrophy in the prefrontal cortex impairs working memory by reducing conduction velocity and increasing action potential failures.

The paper shows that task demands alter sensory and cognitive processing in MT neurons, leading to a division of labor between subpopulations.

This paper shows that continuous attractor networks can optimally integrate circular stimuli and track their average through activity bump phase, with temporal weighting influenced by internal dynamics and sensory inputs.

This paper shows that an attractor model of perceptual decision making can operate in different integration regimes, including a novel 'flexible categorization' regime with a non-monotonic psychometric curve.
