(A) Comparative analyses of main lipid classes and fatty acid contents and relevant indices between control and PD frontal cortex gray matter. Results are expressed as percent of change versus NSL group. Eight cases were analyzed in each group. *P < 0.1 and P < 0.05, respectively. (B) Analyses of the lipid raft-to-cortex ratios for representative lipid classes and fatty acid contents as well as for representative indices in the NSL and PD groups. Cortical and lipid raft were processed individually for each case. *P < 0.05, **P < 0.01 and ***P < 0.005 compared with NSL group.
