Fig. 4: Resting-state functional connectivity within and between networks.
From: Modulating salience network connectivity through olfactory nerve stimulation

A Functional connectivity during olfactory and trigeminal stimulation separately. B Functional connectivity compared between conditions (olfactory vs. trigeminal stimulation). Red lines indicate increased connectivity within networks, while blue lines indicate decreased connectivity between networks. r right hemisphere, l left hemisphere, ACC anterior cingulate cortex, MPFC medial prefrontal cortex, PCC posterior cingulate cortex.
