High-resolution deep brain imaging up to a depth of 1.4 mm using White Dwarf OPCPA

12/6/2021

 
A new microscopy technique developed at EMBL in Heidelberg enables highest imaging resolution for in vivo neuronal activity measurements deep in the brain, driven by a Class 5 Photonics White Dwarf OPCPA. Indirect adaptive optics (AO) in combination with three-photon microscopy reaches near-diffraction-limited resolution of very fine structures in the hippocampus up to a depth of 1.4 mm.

Picture
Fine dendritic processes in the hippocampus can be resolved with the newly developed microscope at EMBL Heidelberg: Scale bar is 20 μm on left pictures showing a depth of 1.243 to 1.423 mm on yz plot; on zoomed region scale bar is 2 µm showing the cross-section of a dendrite.
