[PDF][PDF] The neural representation of sequences: from transition probabilities to algebraic patterns and linguistic trees
A sequence of images, sounds, or words can be stored at several levels of detail, from
specific items and their timing to abstract structure. We propose a taxonomy of five distinct …

[PDF][PDF] Confidence as Bayesian probability: From neural origins to behavior
Research on confidence spreads across several sub-fields of psychology and neuroscience.
Here, we explore how a definition of confidence as Bayesian probability can unify these …

[HTML][HTML] The sense of confidence during probabilistic learning: A normative account
F Meyniel, D Schlunegger… - PLoS computational …, 2015 - journals.plos.org
Learning in a stochastic environment consists of estimating a model from a limited amount
of noisy data, and is therefore inherently uncertain. However, many classical models reduce …

[HTML][HTML] Bifurcation in brain dynamics reveals a signature of conscious processing independent of report
An outstanding challenge for consciousness research is to characterize the neural signature
of conscious access independently of any decisional processes. Here we present a model-…

Studying the neural representations of uncertainty
The study of the brain’s representations of uncertainty is a central topic in neuroscience. Unlike
most quantities of which the neural representation is studied, uncertainty is a property of …

[HTML][HTML] Human inferences about sequences: A minimal transition probability model
The brain constantly infers the causes of the inputs it receives and uses these inferences to
generate statistical expectations about future observations. Experimental evidence for these …

Brain networks for confidence weighting and hierarchical inference during probabilistic learning
Learning is difficult when the world fluctuates randomly and ceaselessly. Classical learning
algorithms, such as the delta rule with constant learning rate, are not optimal. Mathematically…
