Correlation matrix for integrative indexes calculated from fatty acid composition to evaluate the existence of regional relationships. A Average chain length (ACL); B saturated fatty acids (SFA); C Unsaturated fatty acids (UFA); D monounsaturated fatty acids (MUFA); E polyunsaturated fatty acids n-6 series (PUFAn6), F polyunsaturated fatty acids series n-3 (PUFAn3); G double bond index (DBI); H peroxidizability index (PI). Brain regions: CG, cingulate gyrus; CN, caudate nucleus; EC, entorhinal cortex; FC, frontal cortex; H, hippocampus; O, olive; P, putamen; PC, parietal cortex; SN, substantia nigra; T, thalamus; TC, temporal cortex; V, vermis; VC, visual (occipital) cortex
