Spatio-temporal dynamics of lateral Na+ diffusion in apical dendrites of mouse CA1 pyramidal neurons

Joel S. E. Nelson, Jan Meyer, Niklas J. Gerkau, Karl W. Kafitz, Ghanim Ullah, Fidel Santamarı́a, Christine R. Rose

This study investigates the spatio-temporal dynamics of Na+ diffusion in dendrites of mouse CA1 pyramidal neurons using imaging and simulations, finding that normal diffusion rapidly clears local Na+ transients.
