Fig. 1From: Short-latency afferent inhibition and somato-sensory evoked potentials during the migraine cycle: surrogate markers of a cycling cholinergic thalamo-cortical drive?Left panel: Line plots of short-latency afferent inhibition (SAI) at the various interstimulus intervals in healthy volunteers (HV) and in migraine patients recorded between (MO) or during (MI) an attack. Right panel: Bar chart of the MEP slope (mean + sd) of the regression line between the unconditioned MEP amplitude and the 4-conditioned MEPs in the same subject groups.
