Cortical oscillations

…hierarchical structure of intercoupled cortical oscillations correlating with successful comprehension. Experiments show that speech recognition remains largely intact when compressed up to a certain temporal factor [2] and the re-spacing of chunks of incomprehensible compressed speech with silences recovers comprehension. We hypothesize that rhythm-based top-down semantic context inferen

…- targeted to specific phases of cortical oscillations - can refine the interaction of EES with pathological network states. For this, we tailored a real-time system that tracks a selected frequency and used it to deliver stimulation pulses timed to ECOG signals from M2 cortex. We tested the stimulation platform in the unilateral 6-OHDA PD rat model, that resulted in modu

Neural oscillations have been associated with different functions and disorders of the brain. Recently, the non-sinusoidal waveform of oscillations has gained interest as a biomarker for neurological and psychiatric diseases, and as an indicator of underlying network physiology. However, waveform analysis in the time domain has been limited to dominant neuronal oscillations and by pre-selection of waveform features. Here, we contribute a novel Fourier-series waveform analysis that is noise resistant and provides a complete description of waveforms. We applied Fourier-based waveform analysis to
