Decision making under uncertainty in a spiking neural network model of the basal ganglia.

Journal of integrative neuroscience Dec 21, 2016
The mechanisms of decision-making and action selection are generally thought to be under the control of parallel cortico-subcortical loops connecting back to distinct areas of cortex through the basal ganglia and processing motor, cognitive and limbi...

Modulating hierarchical learning by high-definition transcranial alternating current stimulation at theta frequency.

Cerebral cortex (New York, N.Y. : 1991) Apr 4, 2023
Considerable evidence highlights the dorsolateral prefrontal cortex (DLPFC) as a key region for hierarchical (i.e. multilevel) learning. In a previous electroencephalography (EEG) study, we found that the low-level prediction errors were encoded by f...

Electrophysiological Signatures of Hierarchical Learning.

Cerebral cortex (New York, N.Y. : 1991) Jan 22, 2022
Human perception and learning is thought to rely on a hierarchical generative model that is continuously updated via precision-weighted prediction errors (pwPEs). However, the neural basis of such cognitive process and how it unfolds during decision-...

Reversal Learning Task in Children with Autism Spectrum Disorder: A Robot-Based Approach.

Journal of autism and developmental disorders Nov 1, 2015
Children with autism spectrum disorder (ASD) engage in highly perseverative and inflexible behaviours. Technological tools, such as robots, received increased attention as social reinforces and/or assisting tools for improving the performance of chil...
