Behavioral and Neural Changes Induced by a Blended Essential Oil on Human Selective Attention.

Behavioral and Neural Changes Induced by a Blended Essential Oil on Human Selective Attention. Behav Neurol. 2019;2019:5842132 Authors: Liu J, Cai S, Chen D, Wu K, Liu Y, Zhang R, Chen M, Li X Abstract Selective attention refers to the selecting and preferential processing of specific information while simultaneously suppressing irrelevant distractors, activities linked to various cognitive skills and academic achievements. The influence of essential oils on the cognition of humans has been extensively explored. However, the effects of essential oils on human selective attention and the underlying neural mechanisms remain unclear. In the present study, participants were divided into a "blended essential oil" group and a "no essential oil" group and enrolled on a negative priming task, including a control condition and a negative priming condition. The event-related potential technique was used to examine the brain mechanisms underlying the blended essential oil effects on human selective attention. Behavioral results showed that individuals responded more quickly in the negative priming condition when exposed to the blended essential oil. In addition, the blended essential oil eliminated the differences in the P300 amplitude in the postcentral area of the brain between the negative priming condition and the control condition. Moreover, the blended essential oil led to stronger functional connectivity during the task. The present study...

In this study, cynomolgus macaque UGT3A1, UGT3A2, and UGT8A1 cDNAs were isolated and characterized. Amino acid sequences deduced from cynomolgus UGT3A1, UGT3A2, and UGT8A1 cDNAs were highly identical with their human orthologs (93, 96, and 99%, respectively) and were closely clustered in a phylogenetic tree. In the genome, cynomolgus UGT3A and UGT8A genes were located in the regions corresponding to those of their human orthologs. Among the 10 tissue types analyzed, expression of cynomolgus UGT3A1 and UGT3A2 mRNAs was detected in liver, kidney, and testis; the UGT3A1 and UGT3A2 mRNAs were most abundant in liver and testis,...
