Loud noise exposure reduces striatal catecholamine axons and increases glial fibrillary acidic protein (GFAP). Representative striatal TH immunostaining from: control rat (A) and rats sacrificed 24 h (B), and 7 days (C) after 12 h of loud noise exposure. Densitometric analysis of TH-immunostaining is reported in the graph (D). Representative striatal GFAP immunostaining from: control rat (E) and rats sacrificed 24 h (F) and 7 days (G) after 12 h of loud noise exposure. Optical density (OD) of GFAP-immunostaining is reported in the graph (H). White column = control rats; gray column = 12 h noise-exposed rats sacrificed 24 h after exposure; black column = 12 h noise-exposed rats sacrificed 7 days after exposure. *p ≤ 0.05 compared with controls. Bars = (A–C) 660 μm; (E–G) 70 μm.
