Broadband All‐Optical Memtransistor Based on Organic Cocrystals for Noise‐Robust Motion Recognition

open access: yesAdvanced Science, EarlyView.
This work presents an all‐optical synaptic transistor using DTT‐TCNQ organic charge transfer cocrystals, achieving broadband bidirectional modulation (395–808 nm) with highly linear synaptic plasticity (nonlinearity coefficients αp = 0.00191, αd = 0.00305).

Artificial Neuron Based on Electrical Anisotropy from WSe2 Field Effect Transistors

open access: yesAdvanced Science, EarlyView.
An artificial neuron was realized based on the anisotropic mobility of WSe2. Dendritic and axon‐multisynaptic performance of a neuron was achieved with optical and voltage pulses. Recognition accuracy of handwritten digits was obtained to 97% based on the synaptic weight of an artificial neuron.

Quantitative analysis of the interaction between NMDA and AMPA receptors in glutamatergic synapses based on mathematical model

open access: yesNeuroscience Research
NMDA and AMPA receptors are co-localized at most glutamatergic synapses, where their numbers and distribution undergo dynamic changes. Glutamate binds to both the NMDA and AMPA receptors.

Synapse elimination and learning rules co-regulated by MHC class I H2-Db. [PDF]

open access: yes, 2014
The formation of precise connections between retina and lateral geniculate nucleus (LGN) involves the activity-dependent elimination of some synapses, with strengthening and retention of others. Here we show that the major histocompatibility complex (MHC)

A rapamycin-sensitive signaling pathway contributes to long-term synaptic plasticity in the hippocampus [PDF]

open access: yes, 2002
Many forms of long-lasting behavioral and synaptic plasticity require the synthesis of new proteins. For example, long-term potentiation (LTIP) that endures for more than an hour requires both transcription and translation.

Cerebellum to motor cortex paired associative stimulation induces bidirectional STDP-like plasticity in human motor cortex [PDF]

open access: yes, 2012
The cerebellum is crucially important for motor control and adaptation. Recent non-invasive brain stimulation studies have indicated the possibility to alter the excitability of the cerebellum and its projections to the contralateral motor cortex, with ...

Heterosynaptic Memtransistors Based on Switching Operation Mechanism Using Designed Organic/Inorganic Heterostructures for Neuromorphic Electronics

open access: yesAdvanced Science, EarlyView.
Heteroysynaptic memtransistors are fabricated using a combination of π‐conjugated organic semiconductor TCTA and TMDC MoS2 heterostructure with bottom‐contact architecture. Non‐volatile heterosynaptic and homosynaptic functions such as long‐term plasticity and spike‐timing‐dependent plasticity are emulated by drain and gate pulses based on conduction ...

The malleable brain: plasticity of neural circuits and behavior: A review from students to students [PDF]

open access: yes, 2017
One of the most intriguing features of the brain is its ability to be malleable, allowing it to adapt continually to changes in the environment. Specific neuronal activity patterns drive long-lasting increases or decreases in the strength of synaptic ...
