title: Photosensory transduction in Halobacterium salinarium: evidence for a non-linear network of cross-talking pathways.
abstract: Transduction of light stimuli in Halobacterium salinarium is studied by behavioural experiments. Selected patterns of sequential stimuli (impinging on couples of the signalling states of its photoreceptors) show that a simple model integrating different stimuli is inadequate and that non linear interactions between different pathways occur through a network with several connections. The experiments reported herein yield rough but clear-cut information on the level of such interactions and shed new light on earlier findings.
