-methyl-d-aspartate receptor (NMDAR) blockade is crucial for the rapid antidepressant effects of ketamine, the involvement of other mechanisms remains contentious, particularly regarding the role of serotonin, a key neurotransmitter in the target of traditional antidepressants. Here, we demonstrate that ketamine elevates serotonin levels by inhibiting the serotonin transporter (SERT). A...
The human brain is a complex system, whose activity exhibits flexible and continuous reorganization across space and time. The decomposition of whole-brain recordings into harmonic modes has revealed a repertoire of gradient-like activity patterns associated with distinct brain functions. However, the way these activity patterns are expressed over time with their changes in various brain states...
Oculomotor behavior has been shown to be correlated with mental disorders in clinics, making it promising for disease diagnosis. Here we developed a thorough oculomotor test toolkit, involving saccade, smooth pursuit, and fixation, allowing the examination of multiple oculomotor parameters in monkey models induced by psychoactive drugs. Eye movements were recorded after daily injections of...
