Abstract
Review of changes in cortical synchrony in people with post-stroke Hemiparesis: from neuroscience to neurorehabilitation. A review
Neural synchrony is a fundamental phenomenon in brain function, characterized by the temporal coordination of neuronal firing across different brain regions. This process is crucial for various cognitive functions and manifests primarily through the synchronization of oscillatory neuronal responses, especially in the beta/gamma frequency range (20–80 Hz). Stroke can cause significant disruptions in normal patterns of neuronal synchrony. These alterations manifest in several ways, including changes in brain oscillations, which are rhythmic patterns of neuronal activity crucial for various cognitive and motor functions. Recent studies have shown that after a stroke, increases in the power of low-frequency oscillations and decreases in high-frequency oscillations can be observed. These changes in brain oscillations can have a direct impact on the brain's ability to process information and coordinate activities between different regions. Therefore, understanding alterations in neuronal synchrony after a stroke has significant implications for the development of recovery and rehabilitation strategies. For example, interventions aimed at restoring normal patterns of neuronal synchrony could potentially improve functional recovery. Furthermore, monitoring changes in neuronal synchrony and brain criticality could provide valuable indicators of recovery progress and help guide treatment decisions.
