The aim of this study was to determine whether soy‐based and milk‐based infant formula had different effects on the development of brain physiological functions. Electroencephalographic data were collected from infants during quiet wakefulness (n = 71: 26 soy formula fed, 45 milk formula fed) at 3, 6 and 12 months of age. Brain signals were processed using a fast Fourier transformation. An ANOVA examination was applied to the spectral power, with factors of formula group, sex, age, brain area, hemisphere, and frequency band. EEG spectral power increased across age and the increase was greater at 6 months than at 12 months (p<0.01). The spectral power was higher in the frontal and central areas compared to other brain areas (p<0.01), and higher in the left hemisphere relative to the right hemisphere (p<0.01). Males showed higher spectral power than females in most brain areas (p<0.05). There were no differences between formula groups (p>0.05). These findings suggest that soy‐based and milk‐based formula do not differentially affect EEG development in the first year of life. (Supported by USDA CRIS 6251‐51000‐004‐01S).
