Oxytocin and Resting State fMRI
Intranasal Oxytocin and Resting State fMRI in Healthy Volunteers
調査の概要
詳細な説明
Although several fMRI studies investigated the neural correlates of OT administration, only few have focused on the underlying modulatory effects of OT on baseline brain function. While functional MRI examines the neural activity during a certain task, it might be especially interesting to assess the main effect of OT on the basic activity of the human brain in rest. This resting state activity becomes typically evident in the default mode network (DMN), compromising midline structures such as medial frontal cortex, cingulate and precuneus, as well as specific resting state networks .
In fact, a recent study succeeded in demonstrating a modulatory influence of OT. Recent studies were able to show an increased functional connectivity at rest of amygdala to the medial prefrontal cortex (PFC) in a small sample of 15 subjects.
However, distinct subregions of the amygdala seem to be involved in different OT effects. To goal of the present study is to decipher the modulatory effects of OT to subregions of the amygdala in a larger sample using improved anatomical mapping of the seed regions and relate these alterations to individual traits of healthy volunteers. We expected to add evidence to the increase of amygdala - PFC connectivity under OT as well as detailed anatomical mapping of this networks.
