Stereotactic method for customizing UOAs. (a) 3-D CAD brain modeling of macaque V4D using Calabrese¹⁷ atlas plates with highlighted Paxinos¹⁶ regions. A 10-mm section of V4D is selected for 3-D CAD modeling, and the section’s 23 atlas plates have been spaced at $450\mu \mathrm{m}$ simulating their location within the macaque brain. (b) Two 3-D CAD models of the UOA shown virtually implanted in V4D ($13\times 13$ array with TGV and a smaller $8\times 6$); both devices are shown implanted into the 3-D CAD brain model. (c) A completed soda-lime glass $8\times 6$ UOA, and (d) histological results showing successful macaque V4D implantation.
