Visibility and digital art: Blockchain as an ownership layer on the Internet

Visibility of digital art and its ownership can be achieved using blockchain technology as part of a broader solution for the identification, attribution, and payment for digital work. A case study is provided of a firm using the Bitcoin blockchain as part of an integrated solution to identify and authenticate ownership of digital property. An integrated ownership ledger allows for secure attribution, transfer, and provenance of digital property. Blockchain technology enables limited-edition digital property, while Internet-scale web crawl and machine learning shows where and how works are being used on the Internet

Using stereotactic brain atlases for small rodents and nonhuman primates for optrode array customization

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 )
