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

Stochastic di? erential equations model stochastic evolution as time evolves. These models
have a variety of applications in many disciplines and emerge naturally in the study of many …

The suppression of inappropriate actions is critical for flexible behavior. Cortical-basal
ganglia networks provide key gating mechanisms for action suppression, yet the specific …

Several widely accepted models of decision making suggest that, during simple decision
tasks, neural activity builds up until a threshold is reached and a decision is made. These …

Simple perceptual tasks have laid the groundwork for understanding the neurobiology of
decision-making. Here, we examined this foundation to explain how decision-making …

Both the speed and the accuracy of a perceptual judgment depend on the strength of the
sensory stimulation. When stimulus strength is high, accuracy is high and response time is …

Historically, the locus coeruleus–norepinephrine (LC‐NE) system has been implicated in
arousal, but recent findings suggest that this system plays a more complex and specific role …

Intra-individual variability reflects a transient, within-person change in behavioral
performance. It is a common component of aging-related cognitive decline and the …

How does the brain decide between actions? Is it through comparisons of abstract
representations of outcomes or through a competition in a sensorimotor map defining the …

Sequential sampling models have provided a dominant theoretical framework guiding
computational and neurophysiological investigations of perceptual decision-making. While …
