What is time-locked in EEG?

Time-locked in EEG refers to the synchronization of electrical brain activity to a specific event or stimulus. This often involves averaging the EEG signals across multiple trials to isolate and analyze the brain's response to that event, such as a sensory stimulus or cognitive task. Time-locked analysis helps researchers identify event-related potentials (ERPs), which are specific patterns of brain activity associated with particular cognitive processes. This approach is crucial for understanding the temporal dynamics of neural responses in relation to external stimuli.
