Ascorbic Acid in Neural Tissues

Large amounts of ascorbic acid were readily removed from neural tissue by washing with warmed saline solutions. In areas where the original level was highest, such as cortex and cerebellum, a higher percentage was removed than from areas of lower concentration, such as pons-medulla. The residual level in both types of tissue was similar. During scurvy, the ascorbic acid retained in the guinea pig brain is more readily removed by washing than is that of the normal brain.
