Modulatory Effects of Prediction Accuracy on Electroencephalographic Brain Activity During Prediction

open access: yesFrontiers in Human Neuroscience, 2021
Prediction is essential for the efficiency of many cognitive processes; however, this process is not always perfect. Predictive coding theory suggests that the brain generates and updates a prediction to respond to an upcoming event.

Decoding Trans-Saccadic Prediction Error

open access: yesThe Journal of Neuroscience, 2022
We are constantly sampling our environment by moving our eyes, but our subjective experience of the world is stable and constant. Stimulus displacement during or shortly after a saccade often goes unnoticed, a phenomenon called the saccadic suppression of displacement.

The Opioid Receptor Antagonist Naloxone Enhances First-Order Fear Conditioning, Second-Order Fear Conditioning and Sensory Preconditioning in Rats

open access: yesFrontiers in Behavioral Neuroscience, 2021
The opioid receptor antagonist naloxone enhances Pavlovian fear conditioning when rats are exposed to pairings of an initially neutral stimulus, such as a tone, and a painful foot shock unconditioned stimulus (US; so-called first-order fear conditioning;

Surprise beyond prediction error [PDF]

open access: yesHuman Brain Mapping, 2014
AbstractSurprise drives learning. Various neural “prediction error” signals are believed to underpin surprise‐based reinforcement learning. Here, we report a surprise signal that reflects reinforcement learning but is neither un/signed reward prediction error (RPE) nor un/signed state prediction error (SPE).

Two-Bit Embedding Histogram-Prediction-Error Based Reversible Data Hiding for Medical Images with Smooth Area

open access: yesComputers, 2021
During medical treatment, personal privacy is involved and must be protected. Healthcare institutions have to keep medical images or health information secret unless they have permission from the data owner to disclose them.

The Neural Correlates of Cued Reward Omission

open access: yesFrontiers in Human Neuroscience, 2021
Compared to our understanding of positive prediction error signals occurring due to unexpected reward outcomes, less is known about the neural circuitry in humans that drives negative prediction errors during omission of expected rewards. While classical

Cerebellum, Predictions and Errors [PDF]

open access: yesFrontiers in Cellular Neuroscience, 2019
Making predictions and validating the predictions against actual sensory information is thought to be one of the most fundamental functions of the nervous system. A growing body of evidence shows that the neural mechanisms controlling behavior, both in motor and non-motor domains, rely on prediction errors, the discrepancy between predicted and actual ...

Adaptation in Predictive Prosodic Processing in Bilinguals

open access: yesFrontiers in Psychology, 2021
Native language listeners engage in predictive processing in many processing situations and adapt their predictive processing to the statistics of the input.

Estimating Prediction Error: Cross-Validation vs. Accumulated Prediction Error [PDF]

open access: yesCommunications in Statistics - Simulation and Computation, 2010
We study the validation of prediction rules such as regression models and classification algorithms through two out-of-sample strategies, cross-validation and accumulated prediction error. We use the framework of Efron (1983) where measures of prediction errors are defined as sample averages of expected errors and show through exact finite sample ...

Reward prediction error [PDF]

open access: yesCurrent Biology, 2017
In this quick guide, Wolfram Schultz provides an introduction of reward prediction error, exploring the signal of dopamine neurons and describing its potential role in reward accumulation, decision-making and everyday life.
