Evocation of visual responses and deposition of neural tracers:

…The stereotaxic coordinates of visual responses were then used either in the same bird or different birds to guide glass micropipettes to visually responsive loci for the recording and deposition of neural tracers. The glass micropipette (WPI, 1.5 mm outside diameter were pulled in a David Kopf vertical puller (Model 700C) and broken back to produce tips of between 12 and 20 microns internal diameter. These were filled with either biotinylated dextran amine (BDA, Molecular Probes, either 10,000 or 3,000 molecular weight, 10% in phosphate buffered saline (PBS)) or cholera toxin B-chain (choleragenoid; List Laboratories, Campbell, CA, 1% in PBS). …
