Comments P.187 left column 2nd paragraph: "The static length of a cell increases with temperature (primary source) by 0.22 µm/˚C and suggests that the shape itself may also be controlled by cytoplasmic reactions, such as the phosphorylation state of the motor proteins (ref 67)." Primary source abstract: " The present study shows that alteration of temperature changes the length of outer hair cells of the guinea pig cochlea as much as 0.22 micron/degrees C."
