What makes us human?

Higher-order cognitive function makes humans prominent among other creatures. We establish internal representations of everyday experience. In daily life, we continuously receive information about the external world and incorporate it into the previously established internal representations. This process requires continuous acquisition and updating of information. This high-level cognitive function, namely cognitive flexibility, enables us to rapidly adapt to changing environments, an ability critical for survival. Notably, cognitive flexibility is declined in many neuropsychiatric disorders (i.e. schizophrenia, autism), aging, and sleep disorders.

We study molecular-, genetic-, and brain circuit-level mechanisms of cognitive flexibility with the goal to treat cognitive dysfunctions associated with neuropsychiatric disorders, aging, and sleep disorders.

The point certainly deserves further investigation." (Myskiw et al. 2017).
