Visual cortex: two-photon excitement

Curr Biol. 2005 Mar 29;15(6):R205-8. doi: 10.1016/j.cub.2005.03.011.

Abstract

Current in vivo methods for imaging the visual cortex lack the ability to map response properties at the level of single cells. A new technique using two-photon imaging of calcium signals has now overcome this limitation.
