Path‐Decoupled Cation‐Eutaxy III–V van der Waals Memristive Semiconductors for Mitigating the Neuromorphic Accuracy‐Energy Trade‐off

Advanced Materials, EarlyView.
Path‐decoupled III–V van der Waals memtransistors spatially separate ionic and electronic transport to overcome the conventional trade‐off between accuracy and energy in neuromorphic hardware. Mobile K+ ions in the vdW gaps set a wide conductance window, Gmax/Gmin, while gate‐tunable hole conduction lowers programming energy, enabling reliable ...

Rôle des synapses électriques dans le traitement de l'information dans un microcircuit antérograde canonique [PDF]

, 2019
Neurons are electrically excitable nerve cells, communicating with each other at specific points of contacts called synapses. In order to understand how the brain processes information from the outside world and from internal models (memories), it is ...

Monolithic 3D‐Integrated All‐Solid Ion‐Gated Carbon Nanotube Transistors With Tunable Ionic Conductance for Multi‐Timescale Reservoir Computing

Advanced Materials, EarlyView.
A dual‐timescale reservoir based on monolithically 3D (M3D)‐integrated CNT solid ion‐gated transistors is demonstrated. Tunable ionic dynamics and pulse‐engineered operation enable linear and symmetric synaptic updates. The M3D‐integrated array achieves robust temporal encoding and accurate classification of moving MNIST sequences, highlighting its ...

Investigating the effects of homocysteine as an agonist on invertebrate glutamatergic synapses [PDF]

, 2018
Hyperhomocysteinemia (HHcy) in mammals can produce neurological deficits, such as memory loss. The cause of the neurological issues is assumed to be due to homocysteine (HCY) binding to glutamatergic receptors in the central nervous system (CNS).
