Why Neurons Have Thousands of Synapses, A Theory of Sequence Memory in Neocortex [PDF]
Neocortical neurons have thousands of excitatory synapses. It is a mystery how neurons integrate the input from so many synapses and what kind of large-scale network behavior this enables.

Tunable Tactile Synapses Enabled by Erasable Doping in Iongel‐Gated Nanotube Network Transistors
Artificial tactile synaptic sensors are realized by an iongel‐gated single‐walled carbon nanotube (SWCNT) transistor with reversible doping characteristics. The device senses and memorizes tactile stimuli and exhibits gate bias‐dependent excitatory or inhibitory synaptic behavior.

Postsynaptic protein organization revealed by electron microscopy. [PDF]
Neuronal synapses are key devices for transmitting and processing information in the nervous system. Synaptic plasticity, generally regarded as the cellular basis of learning and memory, involves changes of subcellular structures that take place at the ...

Multielement Filament Memristor Enabling Multifunctional Neuromorphic Device
A new type of memristor featuring a hybrid mechanism and multifunctional applications is introduced. The proposed single device combines the alloy metal filament with the oxygen vacancy filament to achieve both resistive and threshold switching with enhanced reliability, mimicking both biological synapses and nociceptors. This study shows that filament‐

Temperature‐Resilient Polymeric Memristors for Effective Deblurring in Static and Dynamic Imaging
A thermally stable organic memristor based on a thiadiazolobenzotriazole (TBZ) and 2,5‐Dioctyl‐3,6‐di(thiophen‐2‐yl)pyrrolo[3,4‐c]pyrrole‐1,4(2H,5H)‐dione (DPP)‐based conjugated polymer is presented, demonstrating reliable, gradual resistance switching across a wide temperature range (153–573 K).

Protein synthesis at synaptic sites on dendrites [PDF]
Studies over the past 20 years have revealed that gene expression in neurons is carried out by a distributed network of translational machinery. One component of this network is localized in dendrites, where polyribosomes and associated membranous ...

This review highlights recent advances in engineering artificial antigen‐presenting cells (aAPCs) as alternatives to dendritic cells for T cell expansion. Key design principles inspired by the immunological synapse are discussed, with emphasis on strategies for polyclonal and antigen‐specific T cell expansion.
