TL;DR: This work re-analyzes the mathematical basis of gradient descent learning in recurrent spiking neural networks (RSNNs) in light of the recent single-cell transcriptomic evidence for cell-type-specific local neuropeptide signaling in the cortex and suggests a computationally efficient on-chip learning method for bio-inspired artificial intelligence.

TL;DR: In this protocol, tissue arrays are imaged using conventional wide-field fluorescence microscopy, which makes it possible to visualize and quantify previously inaccessible features of tissue structure and molecular architecture.

TL;DR: It is shown that near-infrared IOS imaging at wavelengths compatible with semiconductor devices can produce physiologically significant images in mice, even through skull.

TL;DR: In this article, the authors used vertical cavity surface emitting lasers (VCSELs), optical emission filters and PIN photodetectors to realize monolithically integrated, near infrared, fluorescence detection systems.

TL;DR: The Line Emission Mapper (LEM) as discussed by the authors is an X-ray probe for the 2030s that will answer the outstanding questions of the Universe's structure formation, including stellar and black-hole feedback and flows of baryonic matter into and out of galaxies.
