Computational mechanisms of curiosity and goal-directed exploration [PDF]

eLife, 2019
Successful behaviour depends on the right balance between maximising reward and soliciting information about the world. Here, we show how different types of information-gain emerge when casting behaviour as surprise minimisation.

Neural correlates of goal-directed and non-goal-directed movements [PDF]

Proceedings of the National Academy of Sciences, 2019
AbstractWhat are the neural correlates that distinguish goal-directed (G) from non-goal-directed movements (nG)? We investigated this question in the monkey frontal eye field, which is implicated in voluntary control of saccades. We found that only for G-saccades, the variability in spike rate across trials decreased, the regularity of spike timings ...

Perioperative Hemodynamic Optimization in Patients at Risk for Delirium – A Randomized-Controlled Trial

Frontiers in Medicine, 2022
BackgroundPost-operative delirium is common in elderly patients and associated with increased morbidity and mortality. We evaluated in this pilot study whether a perioperative goal-directed hemodynamic optimization algorithm improves cerebral oxygenation

Neural processing of goal and non-goal-directed movements on the smartphone

NeuroImage: Reports, 2023
The discrete behavioral events captured on the smartphone touchscreen may help unravel real-world neural processing. We find that neural signals (EEG) surrounding a touchscreen event show a distinctly contralateral motor preparation followed by visual ...

The Differential Effects of the Amount of Training on Sensitivity of Distinct Actions to Reward Devaluation

Brain Sciences, 2021
Shifting between goal-directed and habitual behaviors is essential for daily functioning. An inability to do so is associated with various clinical conditions, such as obsessive–compulsive disorder (OCD).

Neuromodulatory control of a goal-directed decision. [PDF]

PLoS ONE, 2014
Many cost-benefit decisions reduce to simple choices between approach or avoidance (or active disregard) to salient stimuli. Physiologically, critical factors in such decisions are modulators of the homeostatic neural networks that bias decision ...

Visual adaptation to goal-directed hand actions [PDF]

, 2004
Prolonged exposure to visual stimuli, or adaptation, often results in an adaptation “aftereffect” which can profoundly distort our perception of subsequent visual stimuli.
