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

It is widely believed that the brain performs approximate probabilistic inference to estimate
causal variables in the world from ambiguous sensory data. To understand these …

Human observers combine multiple sensory cues synergistically to achieve greater
perceptual sensitivity, but little is known about the underlying neuronal mechanisms. We …

During perceptual decisions, the activity of sensory neurons correlates with a subject's
percept, even when the physical stimulus is identical,,,,,,,,. The origin of this correlation is …

The variable responses of sensory neurons tend to be weakly correlated (spike-count
correlation, r sc). This is widely thought to reflect noise in shared afferents, in which case r sc …

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

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

The ability to manipulate neural activity with precision is an asset in uncovering neural
circuits for decision-making. Diverse tools for manipulating neurons are available for mice …

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

Goal-directed behavior depends on both sensory mechanisms that gather information from
the outside world and decision-making mechanisms that select appropriate behavior based …
