Fig. 2: The ‘prototypical’ microstates during social attention.
From: Attentive brain states in infants with and without later autism

A Scalp field topography of the four optimal microstate maps estimated from infants with no Family History without a diagnosis of ASD at three years (noFH-noASD) in response to the face with direct gaze stimulus. Normalised amplitude (GFP) in the microstate ranges from −3.5 (blue) to 3.5 (red) microvolts. B Sequence of microstates in response to the face with direct gaze stimulus between −200 and 794 milliseconds (on the x-axis). The blue area indicates that the topography of the scalp field reflects microstate map 1 (M1), green reflects microstate map 2 (M2), red reflects microstate map 3 (M3) and cyan reflects microstate map 4 (M4). On the y-axis, absolute values of the mean GFP for each time-stamp, in microvolts, are indicated.
