EEG Mini-Cap

The Riera High-Density Non-Invasive EEG Mini-Cap

The EEG mini-cap, atlas and source models for Wistar rats represent a new experimental platform for translational neuroscience, bridging the gap between rat and human measurements and enabling non-invasive multi-modal measurements that previously had been unavailable.
