BESA Simulator is a specialized software tool for generating realistic EEG and MEG data. It allows users to place neural sources (dipoles) in a 3D brain model, define their temporal dynamics, and simulate the resulting scalp activity with adjustable noise levels. It is the ideal tool for teaching source analysis and validating signal processing pipelines.
