Brain substates induced by DMT relate to sympathetic output and meaningfulness of the experience

Posted by klaurent UCSF

Kavli Affiliate: Adam Gazzaley | Authors: Lorenzo Pasquini, Alexander Simon, Courtney Gallen, Hannes Kettner, Leor Roseman, Adam Gazzaley, Robin Carhart-Harris and Christopher Timmermann | Summary: N,N-Dimethyltryptamine (DMT) is a serotonergic psychedelic, known to rapidly induce short-lasting alterations in conscious experience, characterized by a profound and immersive sense of physical transcendence alongside rich and vivid auditory […]

Combined Pre-Supernova Alert System with Kamland and Super-Kamiokande

Posted by klaurent Tokyo

Kavli Affiliate: Masayuki Nakahata | First 5 Authors: , , , , | Summary: Preceding a core-collapse supernova, various processes produce an increasing amount of neutrinos of all flavors characterized by mounting energies from the interior of massive stars. Among them, the electron antineutrinos are potentially detectable by terrestrial neutrino experiments such as KamLAND and […]

Cellular and Molecular Basis of Leptin Resistance

Posted by klaurent Rockefeller

Kavli Affiliate: Jeffrey M. Friedman | Authors: Bowen Tan, Kristina Hedbacker, Leah Kelly, Zhaoyue Zhang, Ji-Dung Luo, Joshua D. Rabinowitz and Jeffrey M. Friedman | Summary: Obese humans and diet induced obese mice (DIO) have high leptin levels and fail to respond to the exogenous hormone suggesting that obesity is caused by leptin resistance, the […]

A mathematical theory of relational generalization in transitive inference

Posted by klaurent Columbia

Kavli Affiliate: Vincent Ferrera | Authors: Samuel Lippl, Kenneth Kay, Greg Jensen, Vincent P. Ferrera and L.F. Abbott | Summary: Humans and animals routinely infer relations between different items or events and generalize these relations to novel combinations of items (“compositional generalization”). This allows them to respond appropriately to radically novel circumstances and is fundamental […]

GOALS-JWST: The Warm Molecular Outflows of the Merging Starburst Galaxy NGC 3256

Posted by klaurent Peking

Kavli Affiliate: Claudio Ricci | First 5 Authors: Thomas Bohn, Hanae Inami, Aditya Togi, Lee Armus, Thomas S. -Y. Lai | Summary: We present James Webb Space Telescope (JWST) Integral Field Spectrograph observations of NGC 3256, a local infrared-luminous late-stage merging system with two nuclei roughly 1$;rm{kpc}$ apart, both of which have evidence of cold […]

Continuous Bump Attractor Networks Require Explicit Error Coding for Gain Recalibration

Posted by klaurent Hopkins

Kavli Affiliate: James Knierim | Authors: Gorkem Secer, James J. Knierim and Noah J. Cowan | Summary: Representations of continuous variables are crucial to create internal models of the external world. A prevailing model of how the brain maintains these representations is given by continuous bump attractor networks (CBANs) in a broad range of brain […]

Gene count normalization in single-cell imaging-based spatially resolved transcriptomics

Posted by klaurent Hopkins

Kavli Affiliate: Jean Fan | Authors: Lyla Atta, Kalen Clifton, Manjari Anant and Jean Fan | Summary: Recent advances in imaging-based spatially resolved transcriptomics (im-SRT) technologies now enable high-throughput profiling of targeted genes and their locations in fixed tissues. Normalization of gene expression data is often needed to account for technical factors that may confound […]

Experimental demonstration of scalable cross-entropy benchmarking to detect measurement-induced phase transitions on a superconducting quantum processor

Posted by klaurent UCSB

Kavli Affiliate: Matthew P. A. Fisher | First 5 Authors: , , , , | Summary: Quantum systems subject to random unitary evolution and measurements at random points in spacetime exhibit entanglement phase transitions which depend on the frequency of these measurements. Past work has experimentally observed entanglement phase transitions on near-term quantum computers, but […]
