Rates of filopodial extension and retraction were determined for irradiated and unirradiated growth cone sides by averaging the rate of extension and retraction over the 5-min period. Length measurements were obtained at 30-s intervals and expressed as μm/min. There were no significant differences in the rate of extension or retraction on the control versus irradiated sides of growth cones. Number of filopodia: MII, 87; IgG, 57.
