Increased reactivity of neural marker in ChABC (Sucr 2.5 mol/L) animals vs control and ChABC (Sal) groups. A‐R, Immunofluorescence images of areas used for quantification of βIII‐TUB (blue = DAPI, green = βIII‐TUB), subdivided into dorsal and ventral zones. Histological sections have been further regionalized into rostral, lateral, and caudal areas. Scale bars represent 100 μm. Y, Histological analysis points out the ChABC with sucrose injections significantly increased βIII‐TUB immunoreactivity. (P**<.01 control vs treated; P*<.05 control vs ChABC (Sal))
