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 […]

Intercalation-Induced Near Room-Temperature Ferromagnetism in CrI3 via Synergistic Exchange Pathways

Posted by klaurent UCAS

Kavli Affiliate: Gang Su | First 5 Authors: Qing-Han Yang, Qing-Han Yang, , , | Summary: The development of room-temperature magnetic semiconductors is critical for advancing spintronic technologies, yet van der Waals magnets like CrI3 exhibit intrinsically low Curie temperatures (Tc = 45 K). This study employs first-principles calculations to demonstrate that atom intercalation, particularly […]

Ferroelectric switching of interfacial dipoles in $α$-RuCl$_3$/graphene heterostructure

Posted by klaurent Caltech

Kavli Affiliate: Joseph Falson | Summary:We demonstrate electrically switchable, non-volatile dipoles in graphene/thin hBN/$α$-RuCl$_3$ heterostructures, stabilized purely by interfacial charge transfer across an atomically thin dielectric barrier. This mechanism requires no sliding or twisting to explicitly break inversion symmetry and produces robust ferroelectric-like hysteresis loops that emerge prominently near 30~K. Systematic measurements under strong in-plane […]

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 […]
