Distributed cortico-subcortical networks enable robust speech state detection from sparse intracranial recordings [PDF]

Frontiers in Neuroscience
IntroductionAccurate and reliable detection of speech state transitions is a prerequisite for practical speech brain–computer interfaces (BCIs). While cortical language areas have been extensively studied, it remains unclear whether speech onset ...

High‐accuracy machine learning techniques for functional connectome fingerprinting and cognitive state decoding

Human Brain Mapping, 2023
Abstract The human brain is a complex network comprised of functionally and anatomically interconnected brain regions. A growing number of studies have suggested that empirical estimates of brain networks may be useful for discovery of biomarkers of disease and cognitive state.

Decoding Steady-State Visual Evoked Potentials From Electrocorticography

Frontiers in Neuroinformatics, 2018
We report on a unique electrocorticography (ECoG) experiment in which Steady-State Visual Evoked Potentials (SSVEPs) to frequency- and phase-tagged stimuli were recorded from a large subdural grid covering the entire right occipital cortex of a human ...

Stimulus Design for Visual Evoked Potential Based Brain-Computer Interfaces

IEEE Transactions on Neural Systems and Rehabilitation Engineering, 2023
Visual stimuli design plays an important role in brain-computer interfaces (BCIs) based on visual evoked potentials (VEPs). Variations in stimulus parameters have been shown to affect both decoding accuracy and subjective perception experience, implying ...

Brain decoding of the Human Connectome Project tasks in a dense individual fMRI dataset

NeuroImage, 2023
Brain decoding aims to infer cognitive states from patterns of brain activity. Substantial inter-individual variations in functional brain organization challenge accurate decoding performed at the group level.

Deep Convolutional Neural Network for EEG-Based Motor Decoding

Micromachines, 2022
Brain–machine interfaces (BMIs) have been applied as a pattern recognition system for neuromodulation and neurorehabilitation. Decoding brain signals (e.g., EEG) with high accuracy is a prerequisite to building a reliable and practical BMI.
