Cannabinoids, such as Δ9-tetrahydrocannabinol (THC), produce anxiety at high doses, yet the underlying neural mechanisms remain poorly understood. The anterior cingulate cortex (ACC) sends dense monosynaptic projections to the dorsomedial striatum (DMS). Optogenetic excitation of the ACC → DMS pathway promotes anxiolytic-like behavior, suggesting that its suppression could induce anxiogenic...
