Topic: beta rhythms

Neuromodulation technologies became the safe and effective alternative to treat psychiatric and neurological disorders.We aimed to evaluate the effects of the non-invasive vagus nerve stimulation on psychoemotional state.11 right-handed male volunteers aged 18-22 years participated in the 1st (EEG) study (6 persons-taVNS group and 5-SHAM).62 healthy volunteers 18-49 years old were recruited for 2nd (HRV) study (26-VNS group and 22–Sham).The set of 4 VNS (BrainPatch) was performed at intervals of 3 days with monitoring of HRV and psychometrics.EEG was registered during the rest state (3 min, cl

Beta rhythms are ubiquitous in the motor cortex, and many functional roles were proposed. We recently described a double-dissociation between different beta bands in macaques local field potential (LFP), with low beta (<20Hz) originating in primary motor cortex (M1) and correlating with movement preparation and spontaneous postural dynamics, and high beta (>20Hz) originating in dorsal premotor cortex (PMd) and reflecting spatiotemporal attention (Nougaret et al. 2023, doi:10.1101/2023.03.28.534535). Even within these two bands, individual beta events are highly heterogeneous in their tem
