Nonhallucinogenic psychoplastogens, such as tabernanthalog (TBG), are being developed as potentially safer, more scalable alternatives to psychedelics for promoting neuronal growth and treating various brain conditions. Currently, it is unclear whether 5-hydroxytryptamine 2A (5-HT2A) receptors and immediate early gene (IEG) activation have a role in the neuroplasticity-promoting effects of...
Decreased dendritic spine density in the cortex is a key pathological feature of neuropsychiatric diseases including depression, addiction, and schizophrenia (SCZ). Psychedelics possess a remarkable ability to promote cortical neuron growth and increase spine density; however, these compounds are contraindicated for patients with SCZ or a family history of psychosis. Here, we report the...
