Graph Bispectrum for Nonlinear Mode Interactions
Rahul Singh, Reza Abiri, Walter Besio
We introduce a graph bispectrum formulation for characterizing higher-order interactions in graph signals. While conventional graph spectral methods capture only second-order struc…
Cross-Frequency Bispectral EEG Analysis of Reach-to-Grasp Planning and Execution
Sima Ghafoori, Anna Cetera, Ali Rabiee +5
Neural control of grasping arises from nonlinear interactions across multiple brain rhythms, yet EEG-based motor decoding has largely relied on linear, second-order spectral featur…
Macroscopic EEG Reveals Discriminative Low-Frequency Oscillations in Plan-to-Grasp Visuomotor Tasks
Anna Cetera, Sima Ghafoori, Ali Rabiee +3
The vision-based grasping brain network integrates visual perception with cognitive and motor processes for visuomotor tasks. While invasive recordings have successfully decoded lo…
Precision Enhancement in Sustained Visual Attention Training Platforms: Offline EEG Signal Analysis for Classifier Fine-Tuning
Maryam Norouzi, Mohammad Zaeri Amirani, Yalda Shahriari +1
In this study, a novel open-source brain-computer interface (BCI) platform was developed to decode scalp electroencephalography (EEG) signals associated with sustained attention. T…
Classification of Emerging Neural Activity from Planning to Grasp Execution using a Novel EEG-Based BCI Platform
Anna Cetera, Ali Rabiee, Sima Ghafoori +1
There have been different reports of developing Brain-Computer Interface (BCI) platforms to investigate the noninvasive electroencephalography (EEG) signals associated with plan-to…
A Comparative Study of Conventional and Tripolar EEG for High-Performance Reach-to-Grasp BCI Systems
Ali Rabiee, Sima Ghafoori, Anna Cetera +3
This study aims to enhance BCI applications for individuals with motor impairments by comparing the effectiveness of tripolar EEG (tEEG) with conventional EEG. The focus is on inte…
Wavelet Analysis of Noninvasive EEG Signals Discriminates Complex and Natural Grasp Types
Ali Rabiee, Sima Ghafoori, Anna Cetera +1
This research aims to decode hand grasps from Electroencephalograms (EEGs) for dexterous neuroprosthetic development and Brain-Computer Interface (BCI) applications, especially for…
Bispectrum Analysis of Noninvasive EEG Signals Discriminates Complex and Natural Grasp Types
Sima Ghafoori, Ali Rabiee, Anna Cetera +1
The bispectrum stands out as a revolutionary tool in frequency domain analysis, leaping the usual power spectrum by capturing crucial phase information between frequency components…
