      abstract     = {The quick and reliable detection and identification of a
                      tastant in the mouth regulate nutrient uptake and toxin
                      expulsion. Consistent with the pivotal role of the gustatory
                      system, taste category information (e.g. sweet, salty) is
                      represented during the earliest phase of the taste-evoked
                      cortical response (Crouzet et al., 2015) and different
                      tastes are perceived and responded to within only a few
                      hundred milliseconds, in rodents (Perez et al., 2013) and
                      humans (Bujas, 1935). Currently, it is unknown whether taste
                      detection and discrimination are sequential or parallel
                      processes, i.e. whether you know what it is as soon as you
                      taste it. To investigate the sequence of processing steps
                      involved in taste perceptual decisions, participants tasted
                      sour, salty, bitter, and sweet solutions and performed a
                      taste-detection and a taste-discrimination task. We measured
                      response times and 64-channel scalp electrophysiological
                      recordings, and tested the link between the timing of
                      behavioral decisions and the timing of neural taste
                      representations determined with multivariate pattern
                      analyses. Irrespective of taste and task, neural decoding
                      onset and behavioral response times were strongly related,
                      demonstrating that differences between taste judgments are
                      reflected early during chemosensory encoding. Neural and
                      behavioral detection times were faster for the iso-hedonic
                      salty and sour tastes than their discrimination time. No
                      such latency difference was observed for sweet and bitter,
                      which differ hedonically. Together, these results indicate
                      that the human gustatory system detects a taste faster than
                      it discriminates between tastes, yet hedonic computations
                      may run in parallel (Perez et al., 2013) and facilitate
                      taste identification.},
