Goal-directed behavior requires integrating sensory information with prior knowledge about
the environment. Behavioral biases that arise from these priors could increase positive …

Perceptual decisions are made when sensory evidence accumulated over time reaches a
decision threshold. Because decisions are also guided by prior information, one important …

How do expectations about the identity of a forthcoming visual stimulus influence the neural
mechanisms of perceptual decision making in the human brain? Previous investigations into …

Single neurons in cortical area LIP are known to carry information relevant to both sensory
and value-based decisions that are reported by eye movements. It is not known, however …

Prior information biases the decision process: actions consistent with prior information are
executed swiftly, whereas actions inconsistent with prior information are executed slowly …

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

Choice behavior on simple sensory-motor tasks can exhibit trial-to-trial dependencies. For
perceptual tasks, these dependencies reflect the influence of prior trials on choices that are …

Our choice is influenced by choices we made in the past, but the mechanism responsible for
the choice bias remains elusive. Here we show that the history-dependent choice bias can …

Decision-making behavior has been studied extensively, but the neurophysiological
mechanisms responsible for this remarkable cognitive ability are just beginning to be …

We used a dynamical systems perspective to understand decision-related neural activity, a
fundamentally unresolved problem. This perspective posits that time-varying neural activity …
