A computerized method for decoding
visual evoked potentials involves obtaining a set of brain activity signals, the brain activity signals being recorded from a subject's brain during displaying a set of targets on a display having a display frame duration, at least one target being modulated periodically at a target-specific modulation parameter and decoding a visual
evoked potential (VEP) from the brain activity signals. The decoding includes, at least for the at least one target being modulated at a target-specific modulation parameter, determining a representative time track from the obtained brain activity signals, the representative time track having a length being integer multiples of the display frame duration, analyzing at least one amplitude feature in the representative time track, and determining a most likely target of interest or absence thereof based on said analyzing.
