INFR-GC: Interpretable Feature Representations for Granger Causality in Cortico-muscular Interactions

ICASSP 2025accepted

Understanding the interactions between the central nervous system and muscular responses is essential for developing effective strategies to diagnose and manage movement disorders such as dystonia. This study addresses these complex interactions by introducing a novel non-linear forecasting method f…

SS-ADMM: Stationary and Sparse Granger Causal Discovery for Cortico-Muscular Coupling

ICASSP 2023accepted

Cortico-muscular communication patterns reveal important information about motor control. However, inferring significant causal relationships between motor cortex electroencephalogram (EEG) and surface electromyogram (sEMG) of concurrently active muscles is challenging since relevant processes invol…

Structured Errors-in-Variables Modelling for Cortico-Muscular Coherence Enhancement

ICASSP 2023accepted

Functional coupling between the cortex and muscle is commonly quantified by cortico-muscular coherence (CMC) between electroencephalogram (EEG) and electromyogram (EMG) signals. However, the presence of noise in EEG and EMG often degrades CMC, making it challenging to detect: some healthy subjects w…

Cortico-Muscular Coherence Enhancement Via Sparse Signal Representation

ICASSP 2018accepted

Identifiction of specific cortico-muscular interactions is essential for understanding sensorimotor control. These interactions are commonly studied by analyzing cortico-muscular coherence (CMC) between electroencephalogram (EEG) and surface electromyogram (sEMG) recorded synchronously under a motor…

Delay estimation between EEG and EMG via coherence with time lag

ICASSP 2016accepted

The traditional way to estimate the time delay between the motor cortex and the periphery is based on the estimation of the slope of the phase of the cross spectral density between motor cortex electroencephalogram (EEG) and electromyography (EMG) signals recorded synchronously during a motor contro…
