Laboratory for Systems Molecular Ethology, Center for Brain Science (Team Leader:Yoshihiro Yoshihara)

Research Field

The claustrum is a thin, sheet-like neuronal structure hidden beneath the inner surface of the mammalian cerebral neocortex, whose function is still enigmatic. Its anatomy is quite remarkable in that it receives inputs from and sends outputs to almost all areas of the neocortex. Based on these findings, Crick and Koch (2005) hypothesized that the claustrum may be the neural correlates of consciousness. However, there has been no experimental validation of this daring hypothesis, because it was difficult to selectively manipulate the claustral neurons due to its complex structure and lack of useful molecular/genetic tools. Our laboratory has succeeded in establishing a unique transgenic mouse line in which Cre recombinase is specifically expressed in the neurons of the claustrum ( By taking advantage of this genetically tractable transgenic mouse line, we can now selectively visualize, ablate, excite or silence the claustral neurons toward elucidating its roles in various aspects of higher-order brain functions.
