A fundamental problem in neurobiology is to understand how brain circuits represent
sensory information and how such representations give rise to perception, memory and …

Perceptual decisions arise from the activity of neurons distributed across brain circuits. But,
decoding the mechanisms behind this cognitive operation across brain circuits has long …

The problem of neural coding in perceptual decision making revolves around two
fundamental questions:(i) How are the neural representations of sensory stimuli related to …

The neural mechanism underlying simple perceptual decision-making in monkeys has been
recently conceptualized as an integrative process in which sensory evidence supporting …

▪ Abstract A complex sequence of neural events unfolds between sensory receptor activation
and motor activity. To understand the underlying decision-making mechanisms linking …

Perceptual decisions involve distributed cortical activity. Does information flow sequentially
from one cortical area to another, or do networks of interconnected areas contribute at the …

Perceptual decision making is the act of choosing one option or course of action from a set
of alternatives on the basis of available sensory evidence. Thus, when we make such …

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

The brain constructs representations of objects and concepts based in sensory information
combined with experience. This mental process, that we call perception, is the result of a …

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