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 […]

FBM: Freestanding bilayer microscope for single-molecule imaging of membrane proteins

Kavli Affiliate: Roderick MacKinnon | Authors: Gonzalo Pérez-Mitta, Yeliz Sezgin, Weiwei Wang and Roderick MacKinnon | Summary: Abstract Integral membrane proteins (IMPs) constitute a large fraction of organismal proteomes, playing fundamental roles in physiology and disease. Despite their importance, the mechanisms underlying dynamic features of IMPs, such as anomalous diffusion, protein-protein interactions, and protein clustering, […]

An experimental census of retrons for DNA production and genome editing

Kavli Affiliate: Seth Shipman | Authors: Asim G. Khan, Matías Rojas-Montero, Alejandro González-Delgado, Santiago C. Lopez, Rebecca F. Fang and Seth L. Shipman | Summary: Abstract Retrons are bacterial immune systems that use reverse transcribed DNA as a detector of phage infection. They are also increasingly deployed as a component of biotechnology. For genome editing, […]

Geometry of anisotropic contextual interactions in the visual cortex places fundamental limits on spatial vision

Kavli Affiliate: Anirvan Nandy | Authors: Mitchell P. Morton, Sachira Denagamage, Nyomi V. Hudson and Anirvan S. Nandy | Summary: Crowding, the impaired ability to accurately recognize a target stimulus among distractors, is a major bottleneck in visual perception. The spatial configuration of distractors in relation to the target profoundly influences perceptual fidelity. Notably, when […]

The combination of feedforward and feedback processing accounts for contextual effects in visual cortex

Kavli Affiliate: Kenneth Miller | Authors: Serena Di Santo, Mario Dipoppa, Andreas Keller, Morgane Roth, Massimo Scanziani and Kenneth D Miller | Summary: Abstract Sensory systems must combine local features with context to infer meaning. Accordingly, context profoundly influences neural responses. We developed a unified circuit model demonstrating how feedforward and feedback inputs are integrated […]
