前额叶皮层（PFC）是应激暴露的敏感区域，参与应激应对。用近红外光谱研究了嚼口香糖对应力的影响。然而，当咀嚼口香糖时测量PFC的近红外光谱时，浅层组织（头皮，皮肤，肌肉）的血液流动可能会受到影响。本研究中首先使用的近红外光谱（NIRS）具有较短的距离（1厘米）和通常的（3厘米）源探测器（S-D）回归，可以消除嚼口香糖对浅层组织的影响。本研究的目的是研究嚼口香糖在应对国际情感数字化声音-2 （IADS）中的负面声音（NS）时激活右前额叶皮层（PFC）作为精神压力任务的假设。NS组和Gum组的PFC活动增加，α波出现率增加，心率水平值更高，VAS评分更高，表明“愉快”。咀嚼口香糖激活了右侧PFC活动，同时暴露在IADS的负面声音中作为精神压力任务。
The prefrontal cortex (PFC) is sensitive to the stress exposure and involved in stress coping. And the effects of gum chewing on the stress have been studied using NIRS. However, when measuring NIRS on PFC during gum chewing, blood flows in shallow tissues (scalp, skin, muscle) might be affected. A NIRS used in the present study first, which has a short distance (1 cm) and the usual (3 cm) source-detector (S-D) regression, can allow eliminating shallow tissues effect of gum chewing. The aim of this study was to investigate the hypothesis that gum chewing activates the right prefrontal cortex (PFC) in stress coping against negative sounds (NS) from the International Affective Digitized Sounds-2 (IADS) as a mental stress task. NS showed activation in the right PFC. There was a significant difference between NS, and NS with Gum, where NS with Gum showed an increased PFC activity, increased alpha wave appearance rate, a higher value in heart rate level, and a higher VAS score indicating ‘pleasant’. Gum chewing activated right PFC activity while exposed to negative sounds from IADS as a mental stress task.
