Increasing EEG electrode density improves decoding of visual categories and source localization: an exploratory ultra-high-density EEG study
Communications Engineering, Published online: 24 February 2026; doi:10.1038/s44172-026-00611-wLeonhard Schreiner and colleagues investigate how EEG electrode density shapes visual decoding performance, showing that denser arrays yield higher accuracy. Their findings delineate the practical limits of non-invasive EEG and offer guidance for selecting electrode count and spatial configuration
