Optogenetic activation

Optogenetic activation has been studied in 3 papers since 2016: none in people yet, 3 in animals; 1 in the past year. The research so far is in animals. The newest paper, Mar 26, 2026: “Transcranial Alternating Current Stimulation Improves Post-Anesthesia Motor Function in Aged Mice via Dual striatal Pathways: Dopamine Release and THIN Activation”.
