Spike transmission failures in axons from mouse cortical pyramidal neurons in vivo

Kavli Affiliate: Rafael Yuste | Authors: Netanel Ofer, Victor Hugo Cornejo and Rafael Yuste | Summary: Abstract The propagation of action potentials along axons is traditionally considered to be reliable, as a consequence of the high safety factor of action potential propagation. However, numerical simulations have suggested that, at high frequencies, spikes could fail to […]

Ptycho-endoscopy on a lensless ultrathin fiber bundle tip

Kavli Affiliate: Changhuei Yang | First 5 Authors: Pengming Song, Ruihai Wang, Lars Loetgering, Jia Liu, Peter Vouras | Summary: Synthetic aperture radar (SAR) utilizes an aircraft-carried antenna to emit electromagnetic pulses and detect the returning echoes. As the aircraft travels across a designated area, it synthesizes a large virtual aperture to improve image resolution. […]

Cell spheroid viscoelasticity is deformation-dependent

Kavli Affiliate: Gijsje H. Koenderink | First 5 Authors: Ruben C. Boot, Anouk van der Net, Christos Gogou, Pranav Mehta, Dimphna H. Meijer | Summary: Tissue surface tension influences cell sorting and tissue fusion. Earlier mechanical studies suggest that multicellular spheroids actively reinforce their surface tension with applied force. Here we study this open question […]

The Reliability of Accretion Disk Inclination Derived from X-ray Spectroscopy of Active Galaxies

Kavli Affiliate: Luis C. Ho | First 5 Authors: Rong Du, Yuanze Ding, Luis C. Ho, Ruancun Li, | Summary: The inclination angle of substructures in active galaxies gives insights into physical components from scales of the vicinity of the central black hole to the entire host galaxy. We use the self-consistent reflection spectral model […]

A compact and cost-effective laser-powered speckle visibility spectroscopy (SVS) device for measuring cerebral blood flow

Kavli Affiliate: Changhuei Yang | First 5 Authors: Yu Xi Huang, Simon Mahler, Maya Dickson, Aidin Abedi, Julian M. Tyszka | Summary: In the realm of cerebrovascular monitoring, primary metrics typically include blood pressure, which influences cerebral blood flow (CBF) and is contingent upon vessel radius. Measuring CBF non-invasively poses a persistent challenge, primarily attributed […]
