Neural mechanisms of perceptual decision making have been extensively studied in
experimental settings that mimic stable environments with repeating stimuli, fixed rules, and …

How do changes in the brain lead to learning? To answer this question, consider an artificial
neural network (ANN), where learning proceeds by optimizing a given objective or cost …

Trial history biases and lapses are two of the most common suboptimalities observed during
perceptual decision-making. These suboptimalities are routinely assumed to arise from …

Most theories of behavior posit that agents tend to maximize some form of reward or utility.
However, animals very often move with curiosity and seem to be motivated in a reward-free …

The neural correlates supporting our perceptual experience of the world remain largely
unknown. Recent studies have shown how stimulus detection and related confidence …

The human prefrontal cortex (PFC) constitutes the structural basis underlying flexible
cognitive control, where mixed-selective neural populations encode multiple task features to …

Studies of neural dynamics in lateral orbitofrontal cortex (lOFC) have shown that subsets of
neurons that encode distinct aspects of behavior, such as value, may project to common …

Humans and other animals tend to repeat or alternate their previous choices, even when
judging sensory stimuli presented in a random sequence. It is unclear if and how sensory …

Perception is influenced by sensory stimulation, prior knowledge, and contextual cues,
which collectively contribute to the emergence of perceptual biases. However, the precise …

Natural decisions involve two seemingly separable processes: inferring the relevant task
(task-belief) and performing the believed-relevant task. The assumed separability has led to …
