Comparison of left and right hemisphere models.

Models:Left hemisphere: Genotype ∼ Left Hippocampus + (1|Age).Right hemisphere: Genotype ∼ Right Hippocampus + Right Amygdala + (1|Age).The AIC value of the right hemisphere model is lower than that of the left hemisphere model. The right hemisphere model is also indicated to be a significantly better fit of the data than the left hemisphere model. See Methods for a detailed description of model comparison procedure and AIC calculation.Abbreviations: Hem, Hemisphere; Df, Degrees of freedom; AIC, Akaike's Information Criterion Score; BIC, Bayesian Information Criterion; LogLik, Log-Likelihood.
