To overcome the limitations of single-target optical fibers for 3D brain applications.
To enable patterned light delivery for advanced neuroscientific research.

Main Methods:

Design and fabrication of an array of thin microwaveguides.
Development of a system terminating at a 3D distributed set of points.
Integration of microwaveguide technology for neural targeting.

Main Results:

Successful fabrication of a microwaveguide array.
Demonstration of light delivery to multiple, spatially distributed targets in a 3D pattern.
Validation of the system for brain applications.

Conclusions:

The developed microwaveguide array offers a new solution for multi-target light delivery in the brain.
This technology advances optogenetics and other light-based neuroscience applications.
Enables precise, patterned illumination for complex neural circuit investigations.
