A new direction for grid cells [PDF]
Learning & Behavior, 2015 Krupic, Bauza, Burton, Barry, & O'Keefe (Grid cell symmetry is shaped by environmental geometry. Nature, 518, 232-235, 2015) found that the grids of grid cells in the entorhinal cortex of rats become sparser at the sharp end of a trapezoidal space. This makes grids, and grid cells, unsuitable for measuring distance traveled (odometry) and suggests that

To be a Grid Cell: Shuffling procedures for determining “Gridness” [PDF]
, 2017 Abstract Grid cells in freely behaving mammals are defined by the strikingly regular periodic spatial distribution of their firing. The standard method of identification calculates the “Gridness” of the spatial firing pattern, with significance being defined relative to the 95 th ...

Functional properties of stellate cells in medial entorhinal cortex layer II
eLife, 2018 Layer II of the medial entorhinal cortex (MEC) contains two principal cell types: pyramidal cells and stellate cells. Accumulating evidence suggests that these two cell types have distinct molecular profiles, physiological properties, and connectivity ...

Molecular Oncology, EarlyView.Many patients with urothelial cancer do not benefit from treatment with pembrolizumab, while at risk of severe side effects. Changes in the levels of circulating tumor DNA early during treatment, measured by a simple and affordable assay that can be easily implemented in the clinic, can be used as a prognostic tool to identify these patients.

Modeling Grid Cell Distortions with a Grid Cell Calibration Mechanism
Cyborg and Bionic SystemsThe medial entorhinal cortex of rodents is known to contain grid cells that exhibit precise periodic firing patterns based on the animal’s position, resulting in a distinct hexagonal pattern in space. These cells have been extensively studied due to their potential to unveil the navigational computations that occur within the mammalian brain and ...

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 ...

Optimization of grid design for solar cells [PDF]
, 2010 By theoretical simulation of two grid patterns that are often used in concentrator solar cells, we give a detailed and comprehensive analysis of the influence of the metal grid dimension and various losses directly associated with it during optimization ...
