title: Small injections of fluorescent tracers by iontophoresis or chronic implantation of micropipettes.
abstract: 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.
