A Floating‐Gate Photoelectric Synaptic Transistor Utilizing BP/POx/WSe2 Heterostructure for Neuromorphic Visual Processing

Advanced Science, EarlyView.
In this paper, a novel floating gate transistor (BP/POx/WSe2) is developed, which enables rich synaptic functionality under optoelectronic conditions and can mimic human visual memory. By introducing a two‐path convolutional neural network that synergistically fuses optical and electronic inputs, it can achieve efficient feature extraction and weight ...

Enhanced Single‐Particle Upconversion Imaging via Energy Migration Boosting

Advanced Science, EarlyView.
A core‐shell‐shell Yb3⁺/Er3⁺ UCNP architecture is engineered to balance energy migration and back energy transfer, yielding more than a tenfold enhancement in single‐particle brightness. Leveraging these optimized probes, it achieves long‐term, high‐resolution single‐particle tracking in live neurons, uncovering coordinated transport mechanisms of ...

TNEA Regulates Hippocampal Oscillation by Improving Inhibitory Synaptic Plasticity to Ameliorates Cognitive Impairment in Alzheimer's Disease

Advanced Science, EarlyView.
TNEA improves cognition in 5xFAD mice by modulating parvalbumin‐positive interneurons in hippocampal CA1. TNEA enhances gamma oscillations during rest and theta power during novel object recognition, restoring excitation/inhibition balance. These findings support TNEA as a minimally invasive therapy for Alzheimer's disease.
