- Real-time phase-contrast x-ray imaging: a new technique for the study of animal form and function

Table 2

Effect of duration of x-ray exposure to head on motor control abilities. m/n denotes m animals behaving normally out of n animal trials. Asterisks denote partially limited response (e.g., slow response).

    Exposure time (min) with 25 keV x-rays, 80 μW/mm2
