As the optogenetic field expands its need to target with high specificity only grows more crucial. This work will show a method for customizing soda-lime glass optrode arrays so that fine structures within the brains of small rodents and nonhuman primates can be optically interrogated below the outer cortical layer. An 8 × 6 array is customized for optrode length (400 μm ), optrode width (75 μm ), optrode pitch (400 μm ), backplane thickness (500 μm ), and overall form factor (3.45 mm × 2.65 mm ). The 400 μm long optrode is capable of illuminating the cortical Layer IV of rhesus macaque ( Macaca Fascicularis ) and the motor cortex of small mice ( Mus Musculus ).
