Neurons form transiently stable assemblies that may underlie cognitive functions, including memory formation. In most brain regions, coherent activity is organized by network oscillations that involve sparse firing within a well-defined minority of cells. Despite extensive work on the underlying cellular mechanisms, a fundamental question remains unsolved:(More)
Isolated rat livers were perfused for 6 hours by different types of cell-free synthetic media. Some of the media included perfluoro-compounds as an oxygen carrier. The value of the perfusion medium as blood substitute was judged on the basis of observations and measurements of a number of parameters. These were: secretion of bile, fluid pressure in the(More)
