a Transcranial NIR stimulation of VTA dopamine neurons. In the presence of both UCNPs and ChR2, significant release of dopamine can be detected under the stimulation of NIR. b Transcranial NIR inhibition of neural activity to silence seizure. c Transcranial NIR stimulation of hippocampal engram for memory recall.
