Neuromorphic Light‐Responsive Organic Matter for in Materia Reservoir Computing

Advanced Materials, EarlyView.
In this work we show that light‐responsive adaptive organic matter can store and process information at the matter level, and emulate neuromorphic functionalities such as short term memory, long term memory and visual memory. Besides demonstrating that material dynamics can be exploited for spatio‐temporal event detection and motion perception, we show

Role of Amorphous Phases in Mixed Conduction of Conjugated Regioblock Copolymers for Organic Electrochemical Synaptic Transistors

Advanced Materials, EarlyView.
Critical roles of amorphous and crystalline phases in polymer‐based mixed ionic‐electronic conductors for organic electrochemical synaptic transistors using conjugated regioregular‐block‐regiorandom copolymers are demonstrated. Amorphous phases contribute to gradual polaron formation and strong ion trapping by bipolarons, leading to improved synaptic ...

Frequency Switching Neuristor for Realizing Intrinsic Plasticity and Enabling Robust Neuromorphic Computing

Advanced Materials, EarlyView.
A frequency switching (FS) neuristor is proposed, comprising a Mott memristor and a valence change mechanism (VCM) memristor. The FS neuristor exhibits a multi‐level frequency–voltage (f–V) characteristics, enabling the implementation of neuronal intrinsic plasticity transfer functions.

Artesunate Nanoplatform Targets the Serine–MAPK Axis in Cancer‐Associated Fibroblasts to Reverse Photothermal Resistance in Triple‐Negative Breast Cancer

Advanced Materials, EarlyView.
The artesunate nanoplatform selectively targets ECM CAF, functioning as a GTPase inhibitor through disruption of intracellular serine homeostasis. This metabolic intervention effectively suppresses MAPK cascade activity, which consequently inhibits PTT‐induced CAF to ECM CAF differentiation.

Estrogen and Progesterone Replacement Therapy Prevent Methamphetamine-Induced Synaptic Plasticity Impairment in Ovariectomized Rats [PDF]

Addiction and Health, 2019
Background: Methamphetamine (METH) is one of the most popular psychostimulants which produce long lasting learning and memory impairment. Previous studies have indicated that estrogen and progesterone replacement therapy attenuate cognitive impairment ...

Organic AIE Nanoradiosensitizer Potentiates X‐Ray Triggered Continuous Reactive Oxygen Species Generation for Potent Cancer Radioimmunotherapy

Advanced Materials, EarlyView.
Herein, a glutathione‐responsive system (named THN) is prepared for X‐ray‐triggered sustained ROS generation for efficient antitumor immunotherapy. The double‐promoting ROS generation of THN induced massive immunogenic cancer cell death and polarized M2 macrophages into the M1 phenotype for enhanced antitumor immunotherapy.

Long-term potentiation and the ageing brain

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2003
Abstract Ageing is associated with learning and memory impairments. Data are reviewed that suggest that age-related impairments of hippocampal-dependent forms of memory, may be caused, in part, by altered synaptic plasticity mechanisms in the hippocampus, including long-term potentiation (LTP).
