Electroencephalography (EEG) time-locking. Example shots show the video recordings. Experimental tactile stimuli (row A) were time-locked to recordings through an event detection interface. Experimental noxious stimuli (row B) and cannulation (row C) were time-locked to the EEG recording using high-speed video recordings. t = 0 ms refers to the time when the stimuli first came into contact with the skin. The times shown in ms in the frames refer to these particular examples.
