Abstract
Implantation of cobalt powder in the cerebral cortex of rat determines an epileptogenic focus where two types of reactive astrocytes are observed. The first type is mostly represented in the subcortical white matter but it does exist in the cortex around the implant. Phosphorylase and branching enzyme are both very active in these cells which are filled with glycogen. The second type is limited to the cortex and phosphorylase activity leads to an unbranched polysaccharid. These cells correspond to the "activated astrocytes" described by the authors in a previous paper and observed round irritative lesions which, in the cerebral cortex, produce epileptogenic foci.
