Fluoro-Jade® B staining of the cortex and hippocampus. Fluoro-Jade® B (FJB) staining showed a dense distribution of damaged neurons throughout all layers of the cortex near the sight of impact (a, b). Damaged neurons were also detected in the hippocampus ipsilateral to the injury (d). These neurons were sparsely distributed in the hippocampal CA regions. No FJB staining was detected in either brain region contralateral to the injury (C: cortex; E: hippocampus). FJB: green; Scale bars: 200 μm ( a , c - e ), 100 μm ( b )
