Reduced inhibitory synaptic transmission onto striatopallidal neurons may underlie aging-related motor skill deficits

open access: yesNeurobiology of Disease
Human beings are living longer than ever before and aging is accompanied by an increased incidence of motor deficits, including those associated with the neurodegenerative conditions, Parkinson's disease (PD) and Huntington's disease (HD).

Synaptic plasticity: [PDF]

open access: yesCurrent Biology, 1999
Synaptic activity can induce neurons to synthesize proteins important for cognition and brain development. Recent results suggest this activity-induced protein synthesis is partially mediated by regulated translation within neuronal dendrites.

Engineering Topographical Cues to Enhance Neural Regeneration in Spinal Cord Injury: Overcoming Challenges and Advancing Therapies

open access: yesAdvanced Functional Materials, EarlyView.
Spinal cord injury (SCI) poses significant challenges for regeneration due to a series of secondary injury mechanisms. How to use biomaterial approach to target the failed regeneration after SCI remains a critical challenge. This review systematically evaluates current strategies to optimize biomaterial topographies for neurite outgrowth, axonal ...

Epigenetic modulation of inflammation and synaptic plasticity promotes resilience against stress in mice

open access: yesNature Communications, 2018
Major depressive disorder is associated with abnormalities in the brain and the immune system. Chronic stress in animals showed that epigenetic and inflammatory mechanisms play important roles in mediating resilience and susceptibility to depression ...

Mimicking Synaptic Plasticity: Optoionic MoS2 Memory Powered by Biopolymer Hydrogels as a Dynamic Cations Reservoir

open access: yesAdvanced Functional Materials, EarlyView.
Janus (MoS2) transistors functionalized with sodium alginate (SA) and poly(vinylidene fluoride‐co‐trifluoroethylene) [P(VDF‐TrFE)] exhibit persistent photo‐induced ionic gating, driven by dynamic cation migration at the hybrid interface. This ionic mechanism enables finely tunable photoconductivity and emulates key synaptic plasticity behaviors ...

The roles of STP and LTP in synaptic encoding [PDF]

open access: yesPeerJ, 2013
Long-term potentiation (LTP), a cellular model of learning and memory, is generally regarded as a unitary phenomenon that alters the strength of synaptic transmission by increasing the postsynaptic response to the release of a quantum of neurotransmitter.

Enhanced Switching Performance in Single‐Crystalline PbTiO3 Ferroelectric Memristors for Replicating Synaptic Plasticity

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrated single‐crystalline PbTiO3‐based memristors with atomically sharp interfaces, well‐ordered lattices, and minimal lattice mismatch. The devices exhibited an ON/OFF ratio exceeding 105, high stability, and rich resistance‐state modulation.

Unbiased choice of global clustering parameters for single-molecule localization microscopy

open access: yesScientific Reports, 2022
Single-molecule localization microscopy resolves objects below the diffraction limit of light via sparse, stochastic detection of target molecules. Single molecules appear as clustered detection events after image reconstruction.

Higher‐Order Temporal Dynamics in Complementary Charge Trap Memristor for High‐Dimensional Reservoir Computing

open access: yesAdvanced Functional Materials, EarlyView.
A complementary charge‐trap memristor (CoCTM) featuring a unique current transient with tunable overshoot‐relaxation dynamics is introduced for high‐resolution reservoir computing. By leveraging higher‐order temporal dynamics from engineered trapping layers, the device generates multiple output states from a single input, forming rich, high‐dimensional

Tumor Necrosis Factor and Interleukin-1β Modulate Synaptic Plasticity during Neuroinflammation

open access: yesJournal of Neural Transplantation and Plasticity, 2018
Cytokines are constitutively released in the healthy brain by resident myeloid cells to keep proper synaptic plasticity, either in the form of Hebbian synaptic plasticity or of homeostatic plasticity.
