Audiogenic kindling stimulates aberrant neurogenesis, synaptopodin expression, and mossy fiber sprouting in the hippocampus of rats genetically prone to audiogenic seizures

•Audiogenic kindling enhances proliferation in the DG.•Audiogenic kindling stimulates glutamatergic differentiation of newborn cells.•Hilar cells differentiate faster than neurons of the DG granular layer.•Audiogenic kindling increases sprouting of mossy fibers.•Audiogenic kindling increases synaptopodin expression in the DG.
