Neurophotonics beyond the Surface: Unmasking the Brain's Complexity Exploiting Optical Scattering

Area of Science:

• Neuroscience
• Biomedical Optics
• Physics

Background:

• Studying the brain requires advanced techniques like neurophotonics for minimally invasive cellular and molecular probing.
• Current neurophotonic methods face challenges in imaging depth, field of view, speed, and biocompatibility, largely due to light scattering in brain tissue.

Approach:

• This perspective explores complex media optics, focusing on light propagation in heterogeneous materials, to enhance neuronal readouts.
• Key strategies involve wavefront shaping and computational imaging/sensing techniques that leverage scattering properties.

Key Points:

• Complex media optics offers solutions to overcome light scattering limitations in neuroimaging.
• Wavefront shaping and computational methods are crucial for enhanced optical recordings and structural imaging.
• Merging complex media optics with neurophotonics holds significant potential for advanced in vivo applications.

Conclusions:

• Complex media optics can significantly advance neurophotonics by improving imaging depth, speed, and resolution.
• Further research into merging these fields is essential for developing next-generation brain-probing technologies.
