WebbAnxiolytic effects of CBD are induced with a bell-shaped dose–response curve when administered directly into the dorsolateral periaqueductal gray, an effect mediated by the 5HT 1A R . On the dorsal raphe nucleus, CBD acts as an indirect agonist of the somatodendritic 5-HT 1A autoreceptors, contributing to the anti-emetic effect [ 112 ].
