Forward and convergent remapping of receptive fields from local field potentials in frontal eye fields

Communications Biology
Receptive-field (RF) remapping, produced by attention and corollary discharges (CDs) of saccade commands, has been found in many brain areas. Most remapping studies use neurons’ firing rates of spikes to determine their RFs, and relatively less is known ...

Head direction maps remain stable despite grid map fragmentation

Frontiers in Neural Circuits, 2012
Areas encoding space in the brain contain both representations of position (place cells and grid cells) and representations of azimuth (head direction cells).

Analog Tensor Processing With Carbon Nanotube In‐Memory Matrix Multiplications for Edge Computer Vision Acceleration

Advanced Materials, EarlyView.
This work prototypes a carbon nanotube‐based analog tensor core that performs in‐memory, parallel visual processing. Integrating non‐volatile memories and compact circuits, the core enables high‐speed analog matrix multiplications and can demonstrate accurate three dimensional (3D) spatial transformation and edge detection. With lightweight design, the

Pulmonary vein isolation durability with fluoroscopy or 3D mapping-guided radiofrequency balloon ablation: a mandated remap study

Frontiers in Cardiovascular Medicine
BackgroundEffective balloon positionnking during pulmonary vein isolation (PVI) with a radiofrequency balloon (RFB) is crucial for optimal energy delivery, maximising lesion formation, and preventing gaps.

The hand-reversal illusion revisited

Frontiers in Integrative Neuroscience, 2012
The hand-reversal illusion is a visuomotor illusion that is commonly seen in children’s play. When participants attempt to lift a designated finger while their hands are cross-folded, they are likely to erroneously lift the matched finger of the other ...

Accelerated vegetation succession but no hydrological change in a boreal fen during 20 years of recent climate change

Ecology and Evolution, 2021
Northern mires (fens and bogs) have significant climate feedbacks and contribute to biodiversity, providing habitats to specialized biota. Many studies have found drying and degradation of bogs in response to climate change, while northern fens have ...

A Pollen‐Enhanced Bionic Mechanoreceptor Induced by Asymmetric Ionic Convection in Hydrogel for Sensory‐Augmented Prostheses

Advanced Science, EarlyView.
This work proposed a pollen‐enhanced bionic mechanoreceptor based on ionic convection. Leveraging the ion anchoring effect of the pollen particle, the output performance could be ∼12 times higher than the original state. By employing deep learning models as AI brains, the feasibility of a sensory‐augmented prosthesis consisting of a pollen‐enhanced ...

A Dual‐Perspective View of Kilometer‐Scale Precipitation Data Remapping: Differences Between Conservative and Nonconservative Methods

Meteorological Applications
With the growing use of kilometer‐scale atmospheric models in climate‐scale applications, remapping data from high‐resolution grids to coarser grids and performing statistical diagnostics have become increasingly routine. Precipitation data often exhibit

Experience‐Dependent Reorganization of Hippocampal CA3 Neuronal Ensembles Associates With Memory Generalization

Advanced Science, EarlyView.
Mice can transfer the learned rule of spatial working memory to guide similar but novel tasks. Hippocampal CA3 populational activity dynamically reorganize during memory generalization, shifting from task‐specific to generalized coding over testing days. Sparse yet redundant neural representations of CA3 enable rule transfer and cognitive map formation,
