Figure 10.

(A) Low magnification electron micrograph illustrating a neuron (asterisk) in contact with a dystrophic giant neurite (dn). Note that the portion of the soma in contact with the dystrophic neurite lacks axo-somatic synapses, whereas synapses are established (arrows) in the portion of the soma that is not in contact with the dystrophic neurite. (B) Higher magnification of the axo-somatic synapses that are typically symmetric (GABAergic) synapses (see text for further details). Scale bar, 4 μm in (A); 1 μm in (B).
