Signal intensity in the LGN in response to visual stimuli. Squares indicate individuals with no ecstasy use (median signal intensity 0.03%, range −0.06% to 0.15%). Triangles indicate individuals who have used ecstasy (median signal intensity 0.02%, range −0.06% to 0.05%). Outlines around the symbols indicate overlapping data points.
