When perceptual decisions are coupled to a specific effector, preparatory motor cortical
activity may provide a window into the dynamics of the perceptual choice. Specifically …

The two basic processes underlying perceptual decisions—how neural responses encode
stimuli, and how they inform behavioral choices—have mainly been studied separately …

Cortical circuits encode sensory stimuli through the firing of neuronal ensembles, and also
produce spontaneous population patterns in the absence of sensory drive. This population …

Single sensory neurons can be surprisingly predictive of behavior in discrimination tasks.
We propose this is possible because sensory information extracted from neural populations …

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

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

Identifying the features of population responses that are relevant to the amount of
information encoded by neuronal populations is a crucial step toward understanding …

Single-unit animal studies have consistently reported decision-related activity mirroring a
process of temporal accumulation of sensory evidence to a fixed internal decision boundary …

How the activity of sensory neurons elicits perceptions and guides behavior is central to our
understanding of the brain and is a subject of intense investigation in neuroscience …

Perceptual decision making is the process by which animals detect, discriminate, and
categorize information from the senses. Over the past two decades, understanding how …
