... , characterized by the closure of the parapodia under high irradiance and the reduction of kleptoplast light exposure; and (ii) the activation of a reversible xanthophyll cycle in kleptoplasts, which allows excessive energy to be dissipated. The described mechanisms reduce photoinactivation under high irradiance...

...W. J. Heitler; K. Fraser ABSTRACT A very useful technique to emerge in recent years in the field of neural circuit analysis is in situ dye-visualization and photoinactivation using Lucifer Yellow ( Stewart, 1978 ). This allows direct anatomical identification of neurones during an experiment...

... testing, it is often necessary to wait 1 day for the animal to recover from surgery. It is not yet clear in any system whether a small part of cell inactivated in this way repairs itself or remains inactive after 1 day. In this paper we examine this question of the permanence of LY photoinactivation...
