From: Neuronal and glial changes in the brain resulting from explosive blast in an experimental model
Photomicrographs of the corpus callosum area in (a) a sham control, (b) animal exposed to a single blast, (c) animal exposed to double blast and (d) animal exposed to triple blasts and immunostained for Iba1 a marker for microglia. Activated microglia, which have elongated processes, swollen and somewhat elongated cell bodies and increased immunoreactivity are especially seen with (c) double and (d) triple blast animals
