1. A method for providing and aggregating EEG bioelectrical signal data, using a first EEG biosignal neuroheadset and a second EEG biosignal neuroheadset, the method comprising: establishing a first electrical interface between the first EEG biosignal neuroheadset and a body region of a first user proximal a head region of the first user; establishing a second electrical interface between the second EEG biosignal neuroheadset and a body region of a second user proximal a head region of the second user; providing a stimulus to the first user and to the second user, wherein the stimulus is configured to prompt an action in both the first user and the second user; at a first EEG sensor system of the first EEG biosignal neuroheadset, automatically collecting a first EEG bioelectrical signal dataset from the first user as the first user performs the action; at a first motion sensor system of the first EEG biosignal neuroheadset, collecting a first motion dataset from the first user as the first user performs the action; at a second EEG sensor system of the second EEG biosignal neuroheadset, automatically collecting a second EEG bioelectrical signal dataset from the second user as the second user performs the action; at a second motion sensor system of the second EEG biosignal neuroheadset, collecting a second motion dataset from the second user as the second user performs the action; generating a first anonymized EEG bioelectrical signal dataset from the first EEG bioelectrical signal dataset and a second anonymized EEG bioelectrical signal dataset from the second EEG bioelectrical signal dataset; coupling the first and the second anonymized EEG bioelectrical signal datasets with an action tag characterizing the action; and generating an analysis based upon the first and the second motion datasets and the first and the second anonymized EEG bioelectrical signal datasets, wherein the analysis facilitates elicitation of target brain activity.
