Objectives

Narrative objectives1

In this study, we will expand on previous research, measure brain activity using fMRI, quantify hormones involved in emotions such as oxytocin and corticoids, and investigate the physiological effects that occur with emotional changes caused by odors in newborns. be. Through this research, we will elucidate part of the action mechanism of odor communication by newborns, and further advance this research to scientifically deepen our understanding of human emotions, and attach to newborns as a social outlet for research results. The purpose is to contribute to solving social problems such as the prevention of abuse, such as the development of fragrances that encourage

Assessment

Primary outcomes

We will image changes in brain activity caused by olfactory, visual, and auditory stimuli using fMRI, and compare and analyze the physiological effects that occur with emotional changes caused by odors (especially in newborns) by comparing them with other stimuli. Analysis software such as SPM is used to compare imaging data during stimulus presentation obtained by block design and imaging data at rest.

Key secondary outcomes

In parallel with fMRI imaging, oxytocin and corticoid hormones, which are involved in human emotions, were quantified by collecting saliva. Analysis is performed by t-test. In addition, a psychological questionnaire about odors will be conducted. Statistical analysis examined whether there was a significant difference between the presence and absence of odor stimuli in changes in hormone levels quantified by luminance measurement, and fitted a generalized linear model to the correlation with scores from psychological questionnaires. , to perform a likelihood ratio test.
