The EEG signal is generated by electrical brain cell activity. often described in terms of current dipoles. By applying EEG forward models we can compute the contribution from such dipoles to the electrical potential recorded by EEG electrodes. Forward models are key both for generating understanding and intuition about the neural origin of EEG signals as well as inverse modeling. https://foldlyers.shop/product-category/adapters-2-5-3-5-6-5mm-audio-cables/
