New publication in Nature Methods

Our paper entitled “Fast volumetric calcium imaging across multiple cortical layers using sculpted light” has been published in Nature Methods.

In this work, we present a novel method based on light sculpting that enables unbiased single and dual-plane high-speed (up to 160 Hz) calcium imaging, as well as in vivo volumetric calcium imaging of a mouse cortical column (500x500x500 µm) at single-cell resolution and fast volume rates (3 – 6 Hz). This is achieved by tailoring the point-spread function of our microscope to the structures of interest while maximizing the signal-to-noise ratio while using a home-built fiber laser amplifier with pulses that are synchronized to the imaging voxel speed. Together, these innovations have enabled the near-simultaneous in-vivo recording of calcium dynamics of several thousand active neurons across cortical layers and in the hippocampus of awake behaving mice.

Congratulations to Qian Lin

We congratulate her on the PhD title awarded by the university of Singapore. Previously, she worked on neurobehavioral manifestations of decision making. Recently, Qian Lin joined our group to strengthen our research focus on whole brain imaging to unravel the collective function of brain structures in simple behavioral paradigms.
