Typical in vivo ejection of Ru(bpy)₃²⁺ into the rat thalamus from a 100 μm inner diameter fused silica infusion cannula with 25 μA applied current for 45 min. (A) Fluorescence images overlaid upon bright field images. The combined images are presented left-to-right from anterior (top left) to posterior (bottom right). The scale bars are 1 000 μm. Note triangles indicating probe track from −4.0 to −4.6 mm. (B) Closeup of the image at −4.0 mm from bregma identifying brain regions. (C) Scheme of the experimental setup.
