Neuronal injury induced by hyperthermic seizures in the amygdala, demonstrated using the Gallyas dark-neuron method.A, Significant involvement of the lateral division of the central amygdaloid nucleus (CE-L) is manifested by large numbers of densely silver-stained neurons. B,C, Sections from hyperthermic (B) or normothermic (C) controls contain few stained neurons. D, The distribution of silver-stained neurons in other amygdaloid nuclei, the basomedial (ABM) and basolateral (ABL) nuclei, is shown.E, The presence of argyrophilic neurons in the perirhinal cortex is evident. ALA, Lateral amygdala nucleus; IC, internal capsule; rf, rhinal fissure. Scale bars: A–C, 500 μm;D, E, 200 μm.
