      abstract     = {Previous attempts to uncover a relation between taste
                      processing and weight status have yielded inconclusive
                      results leaving it unclear whether lean and obese
                      individuals process taste differently, and whether group
                      differences reflect differential sensory encoding or
                      evaluative and reward processing. Here, we present the first
                      comparison of dynamic neural processing as assessed by
                      gustatory evoked potentials in obese and lean individuals.
                      Two supra-threshold concentrations of sweet and salty
                      tastants as well as two sizes of blue and green squares were
                      presented to 30 lean (BMI 18.5–25) and 25 obese
                      (BMI > 30) individuals while recording head-surface
                      electroencephalogram (EEG). Multivariate pattern analyses
                      (MVPA) revealed differential taste quality representations
                      from 130 ms until after stimulus offset. Notably, taste
                      representations faded earlier and exhibited a reduced
                      strength in the obese compared to the lean group; temporal
                      generalization analysis indicated otherwise similar taste
                      processing. Differences in later gustatory response patterns
                      even allowed decoding of group membership. Importantly,
                      group differences were absent for visual processing thereby
                      excluding confounding effects from anatomy or
                      signal-to-noise ratio alone. The latency of observed effects
                      is consistent with memory maintenance rather than sensory
                      encoding of taste, thereby suggesting that later evaluative
                      aspects of taste processing are altered in obesity.},
