摘要

Compared with vision and audition, gustation yields weaker and more confound-sensitive scalp (EEG) responses. Here we review gustatory EEG through an observability framework comprising detectability, reproducibility and interpretability. Low-frequency, especially delta-band, activity currently provides the strongest evidence for taste-identity detectability, whereas event-related potentials (ERPs) evidence is stronger for intensity. Spatial and network features remain promising but methodologically constrained. We outline best-practice workflows for cumulative, interpretable gustatory EEG evidence.
