Comments "Neuronal membrane tension is ~10^-2 mN/m (primary source). Might tension vary sufficiently during swell–shrink excursions to impact directly on channels, or is tension regulated near some low set-point? Answers to such fundamental questions require a quantitative knowledge of tension in osmotically perturbed cells and are important for the intimately related issues of cell surface area regulation, cell volume regulation, and cell shape regulation."
