Claim 1 of 5Not checkedA Rockefeller team redesigned three-photon microscopy from the ground up and developed a platform called Three-photon Ultra-Deep Imaging (TrUDI).View evidenceHide evidence
Not checked
A source study was identified, but the evidence comparison for this claim was not completed. No verdict has been assigned.
Claim 2 of 5Not checkedThe article says TrUDI pushes three-photon imaging close to its theoretical limits by reengineering the laser pulse rate, pulse energy, and how pulses are delivered and scanned, while staying within safe sample power exposure limits.View evidenceHide evidence
Not checked
A source study was identified, but the evidence comparison for this claim was not completed. No verdict has been assigned.
Claim 3 of 5Not checkedThe story reports a roughly 250-fold increase in imaging efficiency with TrUDI.View evidenceHide evidence
As statedroughly 250-fold
Not checked
A source study was identified, but the evidence comparison for this claim was not completed. No verdict has been assigned.
Claim 4 of 5Not checkedUsing TrUDI in mice, the team imaged neuronal activity through the entire mouse cortex and into deep structures including the hippocampus and striatum, reaching tissue depths of up to 2.1 millimeters without surgically removing the overlying tissue.View evidenceHide evidence
As statedup to 2.1 millimeters
Not checked
A source study was identified, but the evidence comparison for this claim was not completed. No verdict has been assigned.
Claim 5 of 5Not checkedThe article says tissue analyses found no evidence of inflammation, neuron loss, or DNA damage under the study conditions, supporting the claim that the platform can reach those depths safely.View evidenceHide evidence
