Extended Data Fig. 6: Preparation of the behavioral assay for optogenetic stimulation.
From: Customizable, wireless and implantable neural probe design and fabrication via 3D printing

Preparation for wireless operation. Integrate a 3D-POP and the BLE wireless control module. Check LED operation using the smartphone app. b,c, Preparation for a wired operation: solder wires to a male pin connector (b), and connect a signal generator to a 3D-POP through the wire and apply electrical pulse signals for testing (c).
