Aroma Effect to Learning and ERP verification

This research aims to verify the influence of EOAE (essential oil aroma environment) through a behavioral and ERP(event related potential) study. By this we hope to undercover the brain activity which assists sense, learning and knowledge of aroma. EFL (English as a foreign language) class was performed with an EOAE blend of rosemary cineole 1,8 and lemon. As a result, the target group which learned under EOAE did not have significant difference in result. The survey followed with an ERP evaluation using an odd ball task to measure the degree of attention. As a result, a possible P3a and MMN (Mismatch negativity) amplitude was found to differ between the target and control group. P3a is a subcomponent of P300 which is an attention related component, and MMN is a component that detects auditory deviance in an even sequence of tones. Two other unknown EOAE components that assist only with EOAE were also found.
