Fig. 3. Reduction of P2 and N2 components in RTT.
The figure represents data averaged across conditions (Tone and Phoneme). Each dot corresponds to an individual participant. a Amplitude of the P2 component in TD and RTT groups. Two short horizontal lines indicate the means of the group values. The dashed horizontal green line is drawn at the decision threshold of + 0.63 µV, where RTT and TD participants are discriminated with 100% specificity and 75% sensitivity. b Relationship between P2 component and Rett Syndrome Severity Scores (RSSS) in patients with RTT. Note that larger RSSS values indicate more severe symptoms. c Amplitude of N2 component in TD and RTT participants. Two short horizontal lines indicate the mean of each group.
