Abstract: The human brain exemplifies a highly nonlinear, dynamic, and multiscale complex system, presenting profound challenges for interpretation and real-time monitoring. This talk presents recent advances in signal processing techniques designed to analyze brain dynamics through modalities such as EEG, MEG, and fMRI. We explore modern approaches including time-frequency decomposition, entropy and fractal-based complexity analysis, graph signal processing, and deep neural architectures for extracting high-resolution insights from neural signals.
A significant focus will be on the convergence of joint bio-sensing with secure communication, a critical paradigm for future neurotechnology applications such as brain-computer interfaces, cognitive load estimation, and remote neuro-health monitoring. Here, the fusion of advanced signal processing with secure wireless protocols ensures real-time, privacy-preserving transmission of sensitive brain data across embedded and mobile systems.
Furthermore, the talk will highlight the transformative potential of machine learning in decoding brain states, classifying neurological conditions, and enabling adaptive cognitive systems. We also introduce the role of quantum technologies—particularly in quantum sensing and quantum-secured communication—for achieving ultra-high sensitivity in bio-signal detection and quantum-safe data transfer. This integration unlocks new frontiers in scalable, secure, and intelligent neuro-sensing infrastructures.
