The axons of brain neurons interconnect brain regions, forming functional networks that underlie behaviours, and that engender experience including mood and emotion. Medicines used to treat mood disorders (e.g. Li+ for bipolar disorder, SSRIs for depression) may affect the functional connectivity of brain networks; emerging evidence suggests that these drugs may work, at least in part, by changing the amount and timing of neurotransmitter release, including actions on membrane ion channels that control action potential threshold, duration and conduction velocity in axons, thus influencing the functional connectivity of brain networks. In basic research, we use in vitro brain slice preparations to investigate the effects of current medicines on ion channels and action potentials in brain neurons and axons, and to investigate potential new treatments for mood disorders. In translational research, we collaborate with clinical researchers to study the effects of current and prospective medicines on human brain networks, using EEG tomography in healthy volunteers and patients.
