A multichannel EEG dataset of self-paced (freewill) reach-and-grasp movements recorded from 23 healthy right-handed participants across 49 sessions. On each of 6808 trials the participant freely chose one of four cups, two filled with water and two empty, and decided when to move. Recordings were made at 250 Hz with a 31-channel scalp EEG montage plus EOG and auxiliary channels, to support brain-machine interface research on natural motor execution.

EEG recordings from healthy participants performing self-initiated palmar and lateral reach-and-grasp actions, acquired simultaneously across three recording systems: gel-based laboratory EEG, water-based mobile EEG, and dry-electrode mobile EEG. The dataset supports investigation of the feasibility of decoding natural reach-and-grasp movement-related cortical potentials across EEG acquisition modalities for brain-computer interface applications. It is distributed in BIDS format as part of the MOABB benchmark collection.

This case study records physiological and EEG data from a self-described practitioner of energy medicine who performed directed therapeutic intent on live and damaged cells. Across 60 double-blind treatment and control sessions, cell types (live, dead/x-rayed, or medium only) were randomized and concealed from both the practitioner and the experimenter. Matched control cells treated by a sham therapist provide behavioral measures of cellular outcomes.

This dataset contains simultaneous EEG and BOLD fMRI recordings from 33 healthy participants scanned at Penn State, including resting-state and sleep sessions. EEG was acquired with a 32-channel MR-compatible system, and the data are accompanied by sleep stage scores for each 30-second epoch. It supports investigation of autonomic and neural events during transient arousal changes across sleep.
