Biomimetic SLAM Algorithm Based on Growing Self-Organizing Map
IEEE Access, 2021 A Biomimetic SLAM Algorithm Based on Growing Self-Organizing Map (GSOM-BSLAM), inspired by spatial cognitive mechanism of mammalian hippocampus, is proposed to resolve uncertainty problems in location identification and lack of real-time performance in ...

Segregation of cortical head direction cell assemblies on alternating theta cycles [PDF]
, 2013 High-level cortical systems for spatial navigation, including entorhinal grid cells, critically depend on input from the head direction system. We examined spiking rhythms and modes of synchrony between neurons participating in head direction networks ...

Modeling grid fields instead of modeling grid cells [PDF]
, 2018 A neuron’s firing correlates are defined as the features of the external world to which its activity is correlated. In many parts of the brain, neurons have quite simple such firing correlates. A striking example are grid cells in the rodent medial entorhinal cortex: their activity correlates with the animal’s position in space, defining ‘grid fields ...

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Frontiers in NeuroscienceA central computational problem in spatial navigation is how spatial representations remain stable under noise and uncertainty, and update reliable estimations of continuous variables such as head-direction and position, which respectively rely on the ...

Unique grid cell identification of Croatian official map grids [PDF]
Journal of Maps, 2014 The Unique Grid Cell Identification (UGCI) system was created using the Croatian cartographic map grid system as a basis for development. A short description of the Croatian map grid system is therefore provided. Cartographic map nomenclature is used to uniquely identify map sheets; e.g. grid cells.

FEBS Open Bio, EarlyView.Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

Spatial periodicity in grid cell firing is explained by a neural sequence code of 2-D trajectories
eLifeSpatial periodicity in grid cell firing has been interpreted as a neural metric for space providing animals with a coordinate system in navigating physical and mental spaces.

Smart grids for rural conditions and e-mobility - Applying power routers, batteries and virtual power plants [PDF]
, 2016 Significant reductions of greenhouse gas emission by use of renewable energy sources belong to the common targets of the European Union. Smart grids address intelligent use and integration of conventional and renewable generation in combination with ...

Scaling gridded river networks for macroscale hydrology: Development, analysis, and control of error [PDF]
, 2001 A simple and robust river network scaling algorithm (NSA) is presented to rescale fine‐resolution networks to any coarser resolution. The algorithm was tested over the Danube River basin and the European continent.
