Preservation of long-term memory and synaptic plasticity despite short-term impairments in the Tc1 mouse model of Down syndrome [PDF]

, 2008
Down syndrome (DS) is a genetic disorder arising from the presence of a third copy of the human chromosome 21 (Hsa21). Recently, O’Doherty and colleagues in an earlier study generated a new genetic mouse model of DS (Tc1) that carries an almost complete ...

Neuromorphic Near‐Sensor and In‐Sensor Computing Enabled by Next‐Generation Material‐Based Sensors

Advanced Science, EarlyView.
This Review presents a structural framework that classifies neuromorphic sensing into near‐sensor and in‐sensor architectures, clarifying physical coupling between sensing and computation. The framework connects neural and synaptic device functions with recent advances in optical, mechanical, and chemical sensing, compares energy consumption and ...

Radiofrequency ablation for recurrent hepatocellular carcinoma: 10-year outcomes of local tumor progression vs intrahepatic distant recurrence

Insights into Imaging
Objectives To compare the long-term outcome of radiofrequency ablation (RFA) for local tumor progression (LTP) vs intrahepatic distant recurrence (IDR) in recurrent hepatocellular carcinoma (rHCC), including cases with repeated LTP. Materials and methods

Photonic‐Enabled Energy‐Efficient Transparent Neuromorphic Computing Devices: A Review

Advanced Science, EarlyView.
Transparent photonic neuromorphic computing devices merge optics and brain‐inspired computing to overcome von Neumann bottlenecks with ultrafast, low‐energy processing. By exploiting transparent oxides, 2D materials, phase‐change materials, and hybrid heterostructures, these platforms enable photonic synapses, memory, and logic for see‐through edge ...

Effect of 5-HT4 receptors on LTP.

, 2014
A1: HFS induces LTP under control conditions. A2: The 5-HT4 receptor agonist RS 67333 does not alter LTP. A3: The 5-HT4 receptor antagonists RS 39604 does not modulate LTP. B1: stHFS induces PTP but not LTP under control conditions.

Bidirectional Disulfide Metathesis Enables Recycling of High‐Performance Thermoset Networks

Advanced Science, EarlyView.
A cyclic aromatic disulfide comonomer enables dual‐mode recyclable pDCPD thermosets through bidirectional disulfide metathesis. The resulting networks combine enhanced mechanical performance with thermal reprocessability and chemical depolymerization into reusable oligomeric fragments, allowing regeneration of high‐performance thermosets with minimal ...

Adenylyl Cyclase Subtype 1 is Essential for Late-Phase Long Term Potentiation and Spatial Propagation of Synaptic Responses in the Anterior Cingulate Cortex of Adult Mice

Molecular Pain, 2014
Long-term potentiation (LTP) is a key cellular mechanism for pathological pain in the central nervous system. LTP contains at least two different phases: early-phase LTP (E-LTP) and late-phase LTP (L-LTP). Among several major cortical areas, the anterior
