Brain regions masked with significantly higher regional neuronal activity in the pediatric HIV group compared to healthy controls, showed mostly negative correlation (peak uncorrected p  <  0.01, cluster size ≥ 3) of Social Cognition, negative correlation of Psychomotor Functioning and negative correlation of Abstract Thinking with regional neuronal activity in the 11 pediatric HIV patients. + ve indicate positive correlation and − ve indicate negative correlation.
