A long-standing question in systems neuroscience is how the activity of single neurons gives
rise to our perceptions and actions. Critical insights into this question occurred in the last …

Highlights•Decision-related activity (choice-probabilities [CPs]) in sensory neurons is widely
found.•Correlated variability in sensory neurons limits information in some cases.•The …

During perceptual decisions the activity of sensory neurons covaries with choice, a
covariation often quantified as “choice-probability”. Moreover, choices are influenced by a …

Correlations between trial-to-trial fluctuations in the responses of individual sensory neurons
and perceptual reports, commonly quantified with choice probability (CP), have been widely …

Decisions emerge from the concerted activity of neuronal populations distributed across
brain circuits. However, the analytical tools best suited to decode decision signals from …

Neurons in early sensory cortex show weak but systematic correlations with perceptual
decisions when trained animals perform at psychophysical threshold. These correlations are …

Our understanding of the neural basis of perceptual decision making has been built in part
on relating co-fluctuations of single neuron responses to perceptual decisions on a trial-by …

The activity of cortical neurons in sensory areas covaries with perceptual decisions, a
relationship that is often quantified by choice probabilities. Although choice probabilities …

Many individual behavioral acts are produced by the combined activity of large populations
of broadly tuned neurons, and the neuronal populations for different behaviors can overlap …

Brain regions involved in transforming sensory signals into movement commands are the
likely sites where decisions are formed. Once formed, a decision must be read out from the …
