Figure 1.

Histomorphological examination H&E staining (40×); (A) control group: tissue integrity, general appearance of cells is natural, no changes in neuron size. (B) RF-EMF group: degeneration of neurons in the ventral cochlear nucleus, degradation (black arrowheads), in addition to some decrease in neuron size, shrunken pyknotic cells (white arrowheads). Increased numbers of glial cells (white arrows) and areas with increased vascularization (black arrows). Intense vacuolization in tissue (thin black arrows) and edematous areas.
