Lassen award: Lassen award symposium.

The article discusses several brain-related studies presented at the Lassen award symposium. A. A. Miller and colleagues examined enhanced superoxide production by Nox2-containing NADPH oxidates and its effect on the impairment of endothelial function in the arteries of atherosclerotic mice. Other studies discussed include functional synergy and partial volume correction in brain positron emission tomography by M. Shidahara et al and tissue recovery implications after ischemic stroke by S. Wegener et al.
