Perceptual decision-making is a dynamic cognitive process and is shaped by many factors,
including behavioral state, reward contingency, and sensory environment. To understand …

Several physiology signals, including heart rate and pupil size, have been widely used as
peripheral indices of arousal to evaluate the effects of arousal on brain functions. However …

In decision‐making tasks, neural circuits involved in different aspects of information
processing may activate the central arousal system, likely through their interconnection with …

Pupillometry, the measure of pupil size and reactivity, has been widely used to assess
cognitive processes. Changes in pupil size have been shown to correlate with various …

Decision making between several alternatives is thought to involve the gradual
accumulation of evidence in favor of each available choice. This process is profoundly …

While judging their sensory environments, decision-makers seem to use the uncertainty
about their choices to guide adjustments of their subsequent behaviour. One possible …

The eye's pupil undergoes dynamic changes in diameter associated with cognitive effort,
motor activity and emotional state, and can be used to index brain state across mammalian …

In a competitive game involving an animal and an opponent, the outcome is contingent on
the choices of both players. To succeed, the animal must continually adapt to competitive …

The dissociation between a subjective-criterion performance and forced performance in a
sensory detection can provide critical insights into the neural correlates of sensory …

Understanding how subjects perceive sensory stimuli in their environment and use this
information to guide appropriate actions is a major challenge in neuroscience. To study …
