Small injections of fluorescent tracers by iontophoresis or chronic implantation of micropipettes.
Iontophoresis and chronic micropipette implants were compared for delivery of retrograde fluorescent tracers. Injection sizes and retrograde transport were similar, but implants were more frequently successful than iontophoresis.
