In military veterans with traumatic brain injury, treatment with ibogaine plus magnesium led to dramatic clinical improvements and a favorable safety profile; further studies with state-of-the art safety monitoring will be crucial to unlocking the potential benefits of this psychedelic compound. The horrors of war have been with us throughout human history, and neuropsychiatric aftereffects have garnered increasing attention in recent years.

AbstractSubstance use disorders are associated with neuroimaging abnormalities, but results are heterogeneous across studies and vary across substances, and the causal interpretation of these abnormalities is unknown. We have used network mapping approaches and a functional connectome from a large cohort of healthy participants (n = 1,000) to test whether neuroimaging abnormalities across substance use disorders map to a common brain network.

AbstractThe principle of targeting brain circuits has drawn increasing attention with the growth of brain stimulation treatments such as transcranial magnetic stimulation (TMS), deep brain stimulation (DBS), and focused ultrasound (FUS). Each of these techniques can effectively treat different neuropsychiatric disorders, but treating any given disorder depends on choosing the right treatment target. Here, we propose a three-phase framework for identifying and modulating these targets.
