Grand averages of event-related potentials (ERPs) elicited by startle (left column) and prepulse startle (right column) stimuli in Mexican American young adults. Averages are presented for frontal (Fz) and central (Cz) and parietal (Pz). The N4 component is indicated; solid lines are for participants without a diagnosis of alcohol dependence and dashed lines for participants with a diagnosis of alcohol dependence. X axis represents time (milliseconds, ms) after presentation of the startle stimuli, Y axis is amplitude in microvolts.
