Experimental synchronization between neuroelectrical activity and an elementary electronic chaotic oscillator

These are experimental time series for an electronic chaotic oscillator which is brought to be synchronized with an externally-applied neuroelectric signal, namely the EEG. Recordings from two different physical circuit realizations, as well as SPICE simulations, as provided. Board design materials are also given. These materials are made available to support the replication of the results reported in the associated publication, as well as any further public-domain academic research in the field of neural dynamics, nonlinear electronic circuits, and related aspects, in compliance with the specified license terms and all applicable legal clauses. For any questions regarding these data, the corresponding author of the publication referenced below should be contacted.
