Tutorial unites optical brain imaging tools in a single Python framework

Functional near-infrared spectroscopy (fNIRS) measures brain activity optically based on changes in cortical blood flow. Unlike magnetic resonance imaging, the technique is wearable, so it can be used during movement and outside the lab. Diffuse optical tomography (DOT) extends this principle with improved spatial and depth information. Both are often combined with other modalities, such as electroencephalography (EEG) and physiological signals, to obtain a more complete picture of brain activity in real-world contexts.
