A terahertz grid frequency doubler [PDF]
, 1998 We present a 144-element terahertz quasi-optical grid frequency doubler. The grid is a planar structure with bow-tie antennas as a unit cell, each loaded with a planar Schottky diode.

A Framework for Intelligence and Cortical Function Based on Grid Cells in the Neocortex
Frontiers in Neural Circuits, 2019 How the neocortex works is a mystery. In this paper we propose a novel framework for understanding its function. Grid cells are neurons in the entorhinal cortex that represent the location of an animal in its environment.

Excitatory Microcircuits within Superficial Layers of the Medial Entorhinal Cortex
Cell Reports, 2017 The distinctive firing pattern of grid cells in the medial entorhinal cortex (MEC) supports its role in the representation of space. It is widely believed that the hexagonal firing field of grid cells emerges from neural dynamics that depend on the local

A Generalized Linear Model of a Navigation Network
Frontiers in Neural Circuits, 2020 Navigation by mammals is believed to rely on a network of neurons in the hippocampal formation, which includes the hippocampus, the medial entorhinal cortex (MEC), and additional nearby regions.

Parallel and convergent processing in grid cell, head-direction cell, boundary cell, and place cell networks. [PDF]
, 2013 The brain is able to construct internal representations that correspond to external spatial coordinates. Such brain maps of the external spatial topography may support a number of cognitive functions, including navigation and memory.

Modelling of quasi-optical arrays [PDF]
, 1999 A model for analyzing quasi-optical grid amplifiers based on a finite-element electromagnetic simulator is presented. This model is deduced from the simulation of the whole unit cell and takes into account mutual coupling effects.

A geometric attractor mechanism for self-organization of entorhinal grid modules
eLife, 2019 Grid cells in the medial entorhinal cortex (MEC) respond when an animal occupies a periodic lattice of ‘grid fields’ in the environment. The grids are organized in modules with spatial periods, or scales, clustered around discrete values separated on ...

Optimal Population Codes for Space: Grid Cells Outperform Place Cells [PDF]
, 2012 Rodents use two distinct neuronal coordinate systems to estimate their position: place fields in the hippocampus and grid fields in the entorhinal cortex.

Place Cells, Grid Cells, Attractors, and Remapping [PDF]
Neural Plasticity, 2011 Place and grid cells are thought to use a mixture of external sensory information and internal attractor dynamics to organize their activity. Attractor dynamics may explain both why neurons react coherently following sufficiently large changes to the environment (discrete attractors) and how firing patterns move smoothly from one representation to the ...
