Uncertainty in various forms plagues our interactions with the environment. In a Bayesian statistical framework, optimal inference and prediction, based on unreliable observations in changing contexts, require the representation and manipulation of different forms of uncertainty. We propose that the neuromodulators acetylcholine and norepinephrine play a major role in the brain's implementation of these uncertainty computations. Acetylcholine signals expected uncertainty, coming from known… Expand
Ach and NE : Bayes, uncertainty, attention and learning.
TLDR
It is proposed that the neuromodulatory systems such as acetylcholine (ACh) and norepinephrine (NE) play a major role in the brain's implementation of these uncertainty computations, and they exhibit properties that are consistent with a diverse body of pharmacological, behavioral, electrophysiological, and neurological findings.

FOUR Uncertainty and Neuromodulation : Focus on Acetylcholine and Sustained Attention
Decision making is an essential component of intelligent behavior. Whether interpreting sensory inputs, allocating cognitive resources, or planning actions, the brain constantly makes decisions basedExpand
Pharmacological Fingerprints of Contextual Uncertainty
TLDR
It is proposed that noradrenaline influences learning of uncertain events arising from unexpected changes in the environment, and acetylcholine balances attribution of uncertainty to chance fluctuations within an environmental context, defined by a stable set of probabilistic associations, or to gross environmental violations following a contextual switch.

TLDR
It is postulated that orbitofrontal cortex transforms the stimulus representation through recurrent dynamics, such that a simple error-driven learning rule operating on the transformed representation can implement the Bayesian reinforcement learning update. Expand

Switching Operation Modes in the Neocortex via Cholinergic Neuromodulation
TLDR
This model proposes that cortical acetylcholine favors sensory exploration over exploitation in a cortical microcircuit dedicated to estimating sensory uncertainty, and identifies its interactions with cortical inhibitory interneurons and derives a biophysically grounded computational model able to capture and learn from uncertainty. Expand
Attention, Uncertainty, and Free-Energy
TLDR
It is shown that if the precision depends on the states, one can explain many aspects of attention, including attentional bias or gating, competition for attentional resources, attentional capture and associated speed-accuracy trade-offs. Expand
Phasic norepinephrine: A neural interrupt signal for unexpected events
TLDR
It is proposed that it is unexpected changes in the world within the context of a task that activate the noradrenergic interrupt signal, and this idea is quantified in a Bayesian model of a well-studied visual discrimination task, demonstrating that the model captures a rich repertoire of nor adrenergic responses at the sub-second temporal resolution.

Representations of uncertainty in sensorimotor control
TLDR
Bayesian inference and learning models that have been successful in demonstrating the sensitivity of the sensorimotor system to different forms of uncertainty as well as recent studies aimed at characterizing the representation of the uncertainty at different computational levels are reviewed.

TLDR
It may be useful to establish closer links between neurobiological research on uncertainty and SL, considering particularly mechanisms sensitive to local and global structure in inputs, the degree of input uncertainty, the complexity of the system generating the input, learning mechanisms that operate on different temporal scales and the use of learnt information for online prediction.

TLDR
It is suggested that norepinephrine reports the radical divergence of bottom-up inputs from prevailing top-down interpretations, to influence inference and plasticity. Expand
Acetylcholine in cortical inference
TLDR
A theory of cholinergic modulation in perceptual inference is developed, suggesting that ACh levels reflect the uncertainty associated with top-down information, and have the effect of modulating the interaction between top- down and bottom-up processing in determining the appropriate neural representations for inputs.

Uncertainty and Learning
It is a commonplace in statistics that uncertainty about parameters drives learning. Indeed one of the most influential models of behavioural learning has uncertainty at its heart. However, manyExpand

TLDR
This work shows that subjects internally represent both the statistical distribution of the task and their sensory uncertainty, combining them in a manner consistent with a performance-optimizing bayesian process. Expand

A hierarchical neural architecture is proposed, which implements Bayesian integration of noisy sensory input and top-down attentional priors, leading to sound perceptual discrimination and a possible reconciliation of cortical and neuromodulatory representations of uncertainty. Expand

TLDR
It is suggested that the high levels of acetylcholine that are present during active waking might set the appropriate dynamics for encoding new information in the hippocampus, by partially suppressing excitatory feedback connections and so facilitating encoding without interference from previously stored information.

Locus coeruleus-evoked responses in behaving rats: A clue to the role of noradrenaline in memory
TLDR
Single units of the locus coeruleus are recorded during controlled behavioral situations, in order to relate LC activation to specific behavioral contexts, and show that LC cells respond to novelty or change in incoming information, but do not have a sustained response to stimuli, even when they have a high level of biological significance.
