In theoretical accounts of perceptual decision-making, a decision variable integrates noisy
sensory evidence and determines action through a boundary-crossing criterion. Signals …

Electrophysiological research has isolated neural signatures of decision formation in a
variety of brain regions. Studies in rodents and monkeys have focused primarily on effector …

We frequently need to make timely decisions based on sensory evidence that is weak,
ambiguous, or noisy resulting from conditions in the external environment (eg, a cluttered …

To successfully interact with objects in the environment, sensory evidence must be
continuously acquired, interpreted, and used to guide appropriate motor responses. For …

Both decision making and sensorimotor control require real-time processing of noisy
information streams. Historically these processes were thought to operate sequentially …

In dynamic environments, subjects often integrate multiple samples of a signal and combine
them to reach a categorical judgment. The process of deliberation can be described by a …

The discovery of neural signals that reflect the dynamics of perceptual decision formation
has had a considerable impact. Not only do such signals enable detailed investigations of …

Previous neurophysiological studies of perceptual decision-making have focused on single-
unit activity, providing insufficient information about how individual decisions are …

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

In the last two decades, animal neurophysiology research has made great strides towards
explaining how the brain can enable adaptive action in the face of noisy sensory …
