MAP1B Regulates Cortical Neuron Interstitial Axon Branching Through the Tubulin Tyrosination Cycle

Posted by klaurent Hopkins

Kavli Affiliate: Alex Kolodkin | Authors: Jakub Ziak, Joelle Dorskind, Brian Trigg, Sriram Sudarsanam, Randal Hand and Alex L Kolodkin | Summary: Regulation of directed axon guidance and branching during development is essential for the generation of neuronal networks. However, the molecular mechanisms that underlie interstitial axon branching in the mammalian brain remain unresolved. Here, […]

Rapid learning of neural circuitry from holographic ensemble stimulation enabled by model-based compressed sensing

Posted by klaurent Columbia

Kavli Affiliate: Liam Paninski | Authors: Marcus A. Triplett, Marta Gajowa, Benjamin Antin, Masato Sadahiro, Hillel Adesnik and Liam Paninski | Summary: Abstract Discovering how neural computations are implemented in the cortex at the level of monosynaptic connectivity requires probing for the existence of synapses from possibly thousands of presynaptic candidate neurons. Two-photon optogenetics has […]

Hot electron diffusion, microwave noise, and piezoresistivity in Si from first principles

Posted by dbos Caltech

Kavli Affiliate: Austin J. Minnich | First 5 Authors: Benjamin Hatanpää, Austin J. Minnich, , , | Summary: Ab-initio calculations of charge transport properties in materials without adjustable parameters have provided microscopic insights into electron-phonon interactions which govern charge transport properties. Other transport properties such as the diffusion coefficient provide additional microscopic information and are […]
