title: Visualization of HRP-filled axons in unsectioned, flattened optic tecta of frogs.
abstract: In order to trace individual axons in the tectum, a curved structure, we have modified the HRP method of Adams for use on unsectioned, flattened tecta. Filled axons appear dark and uniformly filled and can be followed without the necessity for reconstructions from serial sections.
