interdisciplinary center for clinical research (IZKF Aachen;

University, as a part of a joint project on alterations of
neural connectivity. In addition, the project was supported
by the German Research Foundation (DFG, IRTG 2150). The

abstract = {Studies with steroid hormones underlined the vital role of
testosterone on social-emotional processing. However, there
is still a lack of studies investigating whether
testosterone modulates network connectivity during
resting-state. Here, we tested how the exogenous application
of testosterone would affect functional connectivity between
regions implicated in emotion regulation. In total, 96 male
participants underwent resting-state fMRI scanning. Before
the measurement, half of the subjects received 5 g
TestimTM gel (containing 50 mg testosterone) and the other
half a corresponding amount of placebo gel. Seeds for the
connectivity analysis were meta-analytically defined. First,
all regions associated with emotion regulation were chosen
via Neurosynth (data driven). Among those, specific seeds
were selected and categorized based on the neural model of
emotion regulation by Etkin and colleagues (Etkin et al.,
2015) (theory-guided). Resting-state connectivity analysis
revealed decreased connectivity between the right DLPFC and
the right amygdala as well as between the VMPFC and the left
IPL for the testosterone group compared to the placebo
group. A complementary dynamic causal modeling (DCM)
analysis on findings from the resting-state connectivity
analysis underlined a bidirectional coupling which was
decreased close to zero by testosterone administration. Our
results demonstrate that testosterone administration
disrupts resting-state connectivity within
fronto-subcortical and fronto-parietal circuits. The
findings suggest that even without a specific task (e.g.
challenge, reward processing) testosterone modulates brain
networks important for social-emotional processing.},
