Does Associative LTP Underlie Classical Conditioning?
, 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 ...

LTP after Stress: Up or Down? [PDF]
, 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.

Advanced Science, EarlyView.WS2‐based in‐memory sensing reservoir computing integrates sensing, memory, and computation in one compact device. It achieves ∼94% N‐MNIST, ∼93% eye motion perception, and ∼89% speech recognition with ultra‐low energy (∼25.5 fJ/spike). The system shows stability at 95% humidity, endurance over 1.5M cycles, and supports synaptic plasticity, enabling ...

Neuron, 2009 The pre/post debate involves the question of whether long-term potentiation (LTP) is mediated by enhancement of release, enhancement of postsynaptic receptors, or both. Recent papers have presented evidence for purely postsynaptic or purely presynaptic changes, and a paper by Ahmed and Siegelbam (in this issue of Neuron) suggests a mechanism by which ...

Advanced Science, EarlyView.An injectable PACmC hydrogel with “rigid island‐flexible chain” architecture is developed, featuring low swelling (49.2% within 7 d), strong wet adhesion (46.5 kPa), and high burst pressure (701 mm Hg), which can achieve rapid hemostasis and long‐term sealing in rabbit and porcine models of hepatic and splenic hemorrhage.

Frontiers 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 ...

Molecular Mechanisms of Early and Late LTP
, 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 ...

CMOS‐Integrated Synaptic Photoreceptor Chip Inspired by Insect Visual Processing
Advanced Science, EarlyView.CMOS‐integrated Si QDs/ReS2 synaptic photoreceptor array mimics the parallel processing and wavelength‐selective strategy of insect vision. By combining intrinsic ultraviolet‐violet sensitivity with synaptic plasticity, the chip enables frontend sensory redundancy reduction without external filters, offering a scalable pathway toward lowpower ...

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