Multifunctional Vertical Bulk‐Heterojunction Transistors With Amorphous GaOx for Neuromorphic Perception‐to‐Decision

open access: yesAdvanced Science, EarlyView.
A multifunctional vertical bulk‐heterojunction transistor (MVBT) with amorphous GaOx integrates four functionalities within a single neuromorphic device. Gate‐source operation enables 254 nm deep‐ultraviolet sensing and threshold neuronal firing, whereas three‐terminal operation supports broadband UV–vis‐NIR synaptic functions and bias‐controlled ...

Arhgef1 Deletion Disrupts Early Cortical Neurogenesis via PAK1 Overactivation and Causes Motor Dysfunction in Adulthood

open access: yesAdvanced Science, EarlyView.
ARHGEF1 plays a pivotal role in both embryonic cortical neurogenesis and adult motor function. During early development, it governs genesis of deep‐layer cortical neurons by negatively regulating RAC1/CDC42‐PAK1‐Cofilin signaling. In adulthood, ARHGEF1 is important for the maintenance of neuronal morphology and activity in the motor cortex, ensuring ...

Engineered Chiral Probiotics Ameliorate MASH via Gut–Liver Axis

open access: yesAdvanced Science, EarlyView.
A chiral gold nanozyme was coated onto the gut commensal bacterium Faecalibacterium duncaniae (F. duncaniae) to create an engineered probiotic. In mouse models of MASH, this orally administered living therapeutic protected the bacterium against oxidative stress, enhanced its gut colonization, reversed steatosis, inflammation, and fibrosis, and improved

Highly Linear Perovskite Synapses for Neuromorphic Computing

open access: yesAdvanced Science, EarlyView.
Voltage spikes applied to an Au/ACI‐phase perovskite/ITO memristor emulate the ionic signaling of a biological synapse, generating a tunable postsynaptic current. The vertically aligned perovskite film confines iodide‐vacancy migration, enabling highly linear, and symmetric conductance updates with 100 states and 5.5 aJ per event. Such synapses sustain

Propofol Modulates Fear Memory Reconsolidation by Inhibiting D2 Receptor‐Expressing Neurons in the Medial Prefrontal Cortex

open access: yesAdvanced Science, EarlyView.
This study shows that propofol modulates fear‐memory reconsolidation in mice. It works by suppressing D2 receptor‐expressing neurons within the medial prefrontal cortex and their connections to the basolateral amygdala. D2‐receptor agonists reproduce this fear‐reducing effect, offering potential non‐anesthetic therapeutic strategies for trauma‐related ...

Membrane‐Targeted Nanoparticles for Neuronal Photomodulation

open access: yesAdvanced Science, EarlyView.
Immobilizing gold nanoparticles on the neural interface using a bioorthogonal approach generates localized heat upon exposure to near‐infrared light, temporarily inhibiting primary neuronal activity without damaging the cells. This precise placement and retention of nanoparticles at the cell membrane expand the strategies for non‐invasive neural ...
