Calcium, magnesium, sodium, and potassium levels were determined in brain tissues of mice subjected to gravitational acceleration in the longitudinal direction. Although no significant changes occur in calcium and magnesium levels, potassium levels markedly increase while sodium levels decrease following exposure to 5 and 10 Gz for 5 min. The electrolyte changes are of long duration and remain for periods greater than 5 h.
