Decoding of image properties from single-trial visual evoked potentials recorded by ultra-high-density EEG.

ABSTRACT: Visual evoked potentials (VEPs) recorded by encephalography (EEG) allow us to study the neuronal activity non-invasively and in high temporal resolution. Traditionally, EEG analyses have relied on univariate group-level statistics and trial averaging to detect effects. However, recent advances in high-density EEG enable the investigation of brain responses at the single-subject and single-trial level. In this study, we combine ultra-high-density (uHD) EEG with cross-validated single-trial decoding to bridge both approaches, improving generalizability and reproducibility. Study participants were shown a diverse set of random images while 512 channels from the uHD system recorded their EEG over the occipital lobe.
