Ventral pallidum GABA and glutamate neurons drive approach and avoidance through distinct modulation of VTA cell types

Posted by klaurent July 12, 2023July 24, 2023UCSD / Salk

Kavli Affiliate: Andrea Hasenstaub | Authors: David A. McCormick, Yousheng Shu and Andrea R Hasenstaub | Summary: The ventral pallidum (VP) contains GABA and glutamate (Glut) neurons projecting to ventral tegmental area (VTA) whose stimulation drives approach and avoidance, respectively. Yet little is known about the cell-type-specific mechanisms by which VP projections to VTA drive […]

The h-current controls cortical recurrent network activity through modulation of dendrosomatic communication

Posted by klaurent July 12, 2023July 24, 2023UCSF

Kavli Affiliate: Andrea Hasenstaub | Authors: David A. McCormick, Yousheng Shu and Andrea R Hasenstaub | Summary: A fundamental feature of the cerebral cortex is the ability to rapidly turn on and off maintained activity within ensembles of neurons through recurrent excitation balanced by inhibition. Here we demonstrate that reduction of the h-current, which is […]

Resolving Non-identifiability Mitigates Bias in Models of Neural Tuning and Functional Coupling

Posted by klaurent July 12, 2023July 24, 2023UCSF

Kavli Affiliate: Kristofer Bouchard, Loren Frank, Christoph Kirst | Authors: Pratik Sachdeva, Ji Hyun Bak, Jesse A Livezey, Loren Frank, Christoph Kirst, Sharmodeep Bhattacharyya and Kristofer Bouchard | Summary: In the brain, all neurons are driven by the activity of other neurons, some of which maybe simultaneously recorded, but most are not. As such, models […]

An Exploration of AGN and Stellar Feedback Effects in the Intergalactic Medium via the Low Redshift Lyman-$α$ Forest

Posted by dbos MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Megan Taylor Tillman, Blakesley Burkhart, Stephanie Tonnesen, Simeon Bird, Greg L. Bryan | Summary: We explore the role of galactic feedback on the low redshift Lyman-$alpha$ (Ly$alpha$)~forest ($z lesssim 2$) statistics and its potential to alter the thermal state of the intergalactic medium. Using the Cosmology and […]

The Atacama Cosmology Telescope: Galactic Dust Structure and the Cosmic PAH Background in Cross-correlation with WISE

Posted by dbos July 12, 2023Stanford

Kavli Affiliate: Susan E. Clark | First 5 Authors: Rodrigo Córdova Rosado, Brandon S. Hensley, Susan E. Clark, Adriaan J. Duivenvoorden, Zachary Atkins | Summary: We present a cross-correlation analysis between $1’$ resolution total intensity and polarization observations from the Atacama Cosmology Telescope (ACT) at 150 and 220 GHz and 15$”$ mid-infrared photometry from the […]

Surfaces in which every point sounds the same

Posted by klaurent July 12, 2023Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Emmett L. Wyman, Yakun Xi, , | Summary: We address a maximally structured case of the question, "Can you hear your location on a manifold," posed in arXiv:2304.04659 for dimension $2$. In short, we show that if a compact surface without boundary sounds the same […]

Multimodal Operando X-ray Mechanistic Studies of a Bimetallic Oxide Electrocatalyst in Alkaline Media

Posted by dbos July 12, 2023Cornell

Kavli Affiliate: Hector D. Abruna | First 5 Authors: Jason J. Huang, Yao Yang, Daniel Weinstock, Colin R. Bundschu, Jacob P. C. Ruff | Summary: Furthering the understanding of the catalytic mechanisms in the oxygen reduction reaction (ORR) is critical to advancing and enabling fuel cell technology. In this work, we use multimodal operando synchrotron […]

Rethinking Mitosis Detection: Towards Diverse Data and Feature Representation

Posted by klaurent July 12, 2023July 24, 2023Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Hao Wang, Jiatai Lin, Danyi Li, Jing Wang, Bingchao Zhao | Summary: Mitosis detection is one of the fundamental tasks in computational pathology, which is extremely challenging due to the heterogeneity of mitotic cell. Most of the current studies solve the heterogeneity in the technical aspect by […]
