Extracellular space diffusion modelling identifies distinct functional advantages of archetypical glutamatergic and GABAergic synapse geometries

Paula Gimenez, Rohisha T. Shakya, Fidel Santamarı́a, Jan Tønnesen

The paper models diffusion in the brain's extracellular space to show how synapse geometries affect signaling, revealing functional advantages of glutamatergic and GABAergic synapse shapes.

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

Joel S. E. Nelson, Jan Meyer, Niklas J. Gerkau…·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.
