Circuit inhibition promotes the dynamic reorganization of prefrontal task encoding to support cognitive flexibility

Posted by dbos UCSF

Kavli Affiliate: Vikaas Sohal | Authors: Carlos Johnson-Cruz, Kathleen K.A. Cho and Vikaas S. Sohal | Summary: The mammalian prefrontal cortex encodes variables related to goal-directed behavior, and enables flexibility during environmental changes, making it critical to understand how the dynamic updating vs. stable maintenance of different encodings contribute to behavioral adaptation. We addressed this […]

Causal Dynamics of Social Gaze in Primate Prefrontal-Amygdala Networks Revealed by Dynamic Bayesian Modeling

Posted by dbos Yale

Kavli Affiliate: Anirvan Nandy | Authors: Feng Xing, Siqi Fan, Olga Dal Monte, Monika Jadi, Steve Chang and Anirvan Nandy | Summary: Social gaze is a fundamental channel of primate communication, shaping dynamic interactions and fostering mutual understanding. While prior studies have mapped the behavioral correlates of social gaze across the prefrontal-amygdala circuits, the causal […]

Elliptic Genera of 2d $mathcalN=(0,1)$ Gauge Theories

Posted by klaurent Tokyo

Kavli Affiliate: Masahito Yamazaki | Summary:We derive an exact residue formula for the elliptic genera of 2d $mathcalN=(0,1)$ gauge theories. We find a new residue prescription which recovers the Jeffery-Kirwan residue prescription for $mathcalN=(0,2)$ theories. We apply the formula to the Gukov-Pei-Putrov model and analyze the phase structure of the theory. | Search Query: arXiv […]

Learning More by Seeing Less: Structure First Learning for Efficient, Transferable, and Human-Aligned Vision

Posted by klaurent Caltech

Kavli Affiliate: Yuchong Tai | First 5 Authors: Tianqin Li, Tianqin Li, , , | Summary: Despite remarkable progress in computer vision, modern recognition systems remain fundamentally limited by their dependence on rich, redundant visual inputs. In contrast, humans can effortlessly understand sparse, minimal representations like line drawings, suggesting that structure, rather than appearance, underlies […]

Gate reflectometry in a minimal Kitaev chain device

Posted by klaurent Delft

Kavli Affiliate: Srijit Goswami | Summary:Hybrid quantum dot (QD)-superconductor system can be used to realize Majorana zero modes in artificial Kitaev chains. These chains provide a promising platform for the realization of Majorana qubits. Radio-frequency (RF) gate reflectometry is a fast, non-invasive, and sensitive technique that can be used to read out such qubits. In […]
