The collective activity of a population of neurons, beyond the properties of individual cells, is
crucial for many brain functions. A fundamental question is how activity correlations between …

Trial-to-trial variability in the execution of movements and motor skills is ubiquitous and
widely considered to be the unwanted consequence of a noisy nervous system. However …

Modeling human cognition is challenging because there are infinitely many mechanisms
that can generate any given observation. Some researchers address this by constraining the …

How is it that thoroughly physical material beings such as ourselves can think, dream, feel,
create and understand ideas, theories and concepts? How does mere matter give rise to all …

When facing uncertainty, adaptive behavioral strategies demand that the brain performs
probabilistic computations. In this probabilistic framework, the notion of certainty and …

Successful speech perception requires that listeners map the acoustic signal to linguistic
categories. These mappings are not only probabilistic, but change depending on the …

All adaptive organisms face the fundamental tradeoff between pursuing a known reward
(exploitation) and sampling lesser-known options in search of something better …

Computational strategies used by the brain strongly depend on the amount of information
that can be stored in population activity, which in turn strongly depends on the pattern of …

Human perceptual decisions are often described as optimal. Critics of this view have argued
that claims of optimality are overly flexible and lack explanatory power. Meanwhile …

Decision-makers often arrive at different choices when faced with repeated presentations of
the same evidence. Variability of behavior is commonly attributed to noise in the brain's …
