Plasticity-related microRNA and their potential contribution to the maintenance of long-term potentiation

open access: yesFrontiers in Molecular Neuroscience, 2015
Long-term potentiation (LTP) is a form of synaptic plasticity that is an excellent model for the molecular mechanisms that underlie memory. LTP, like memory, is persistent, and both are widely believed to be maintained by a coordinated genomic response ...

Precedent post-LTP protocol may prevent pre-LTP induction.

open access: yes, 2013
A. Diagram illustrating combined protocols in which pre-LTP protocol follows post-LTP protocol with the delay of 0.5 s. B, C. The combined protocols, delivered to thalamic input, resulted in potentiation of EPSP to 162 ± 14% of baseline amplitude at ...

LTP after Stress: Up or Down? [PDF]

open access: yes, 2007
When an organism is exposed to a stressful situation, corticosteroid levels in the brain rise. This rise has consequences for behavioral performance, including memory formation.

Gut Microbial Release of Ferulic Acid From Germinated Quinoa Alleviates Obesity‐Associated Cognitive Impairment by Activating Hippocampal Mitophagy Associated with PINK1/Parkin Pathway

open access: yesAdvanced Science, EarlyView.
Liberation of ferulic acid by gut microbial feruloyl esterase mediates cognitive enhancement of germinated quinoa (GQF) on obese mice. Ferulic acid enriched in GQF is released by gut microbes Roseburia hominis and R. intestinalis and subsequently mediates the neuroprotective effects of GQF on obesity‐induced cognitive decline by activating hippocampal ...

Wake‐Up and Fatigue under Electrical Cycling in HfO2‐Based Ferroelectrics: Mechanisms and Strategies toward Reliable Devices

open access: yesAdvanced Science, EarlyView.
HfO2‐based ferroelectrics exhibit wake‐up and fatigue behaviors during electrical cycling, significantly affecting device endurance and reliability. These phenomena are governed by defect dynamics, including oxygen vacancy redistribution and charge trapping.

Molecular Mechanisms of Early and Late LTP

open access: yes, 2019
LTP is the most intensively studied cellular model of the memory and generally divided at least two distinct phases as early and late. E-LTP requires activation of CaMKII that initiates biochemical events and trafficking of proteins, which eventually ...

Battery‐Inspired Electrochemical Synapses for Neuromorphic Applications

open access: yesAdvanced Science, EarlyView.
Battery‐ion‐inspired synaptic devices integrate diverse electrolyte systems (solid, ion‐gel, liquid) with transition metal oxides, two‐dimensional materials, and organic channels to regulate ion‐electron coupling. By tailoring ion transport and host interactions, these platforms enable controllable plasticity and energy‐efficient implementations for ...

Does Associative LTP Underlie Classical Conditioning?

open access: yes, 1994
A major goal in cognitive neuroscience is to identify the cellular substrates that underlie learning and memory. One prominent approach toward achieving this goal has been to study the enhancement of synaptic transmission produced by high-frequency ...

Coexisting Volatile and Nonvolatile Switching in 3D ALD‐IGZO Vertical RRAM for Fully Hardware‐Based Wide Reservoir Computing

open access: yesAdvanced Science, EarlyView.
A conformal ALD‐IGZO vertical RRAM integrates volatile and nonvolatile switching within a compact 2F architecture. Before forming, tunable volatile dynamics provide fading‐memory reservoir states, while after forming, stable multilevel conductance modulation enables hardware readout.

Neuromorphic Devices and Computing for Sensing, Memory, and Control

open access: yesAdvanced Science, EarlyView.
This review introduces neuromorphic devices made from diverse materials. These devices mimic neuronal functions and architectures and, when integrated with artificial or biological computing, can form closed loops with neurons for pressure, optical, acoustic, and biochemical sensing and modulation.
