Tetris in the Nervous System: What Principles of Neuronal Tiling Can Tell Us About How Glia Play the Game

open access: yesFrontiers in Cellular Neuroscience, 2021
The precise organization and arrangement of neural cells is essential for nervous system functionality. Cellular tiling is an evolutionarily conserved phenomenon that organizes neural cells, ensuring non-redundant coverage of receptive fields in the ...

Glial Tiling in the Insect Nervous System

open access: yesFrontiers in Cellular Neuroscience, 2022
The Drosophila nervous system comprises a small number of well characterized glial cell classes. The outer surface of the central nervous system (CNS) is protected by a glial derived blood-brain barrier generated by perineurial and subperineurial glia ...

Glial Patchwork: Oligodendrocyte Progenitor Cells and Astrocytes Blanket the Central Nervous System

open access: yesFrontiers in Cellular Neuroscience, 2022
Tiling is a developmental process where cell populations become evenly distributed throughout a tissue. In this review, we discuss the developmental cellular tiling behaviors of the two major glial populations in the central nervous system (CNS ...

Channel-independent function of UNC-9/Innexin in spatial arrangement of GABAergic synapses in C. elegans

open access: yeseLife, 2022
Precise synaptic connection of neurons with their targets is essential for the proper functioning of the nervous system. A plethora of signaling pathways act in concert to mediate the precise spatial arrangement of synaptic connections.

Quantifying Glial-Glial Tiling Using Automated Image Analysis in Drosophila

open access: yesFrontiers in Cellular Neuroscience, 2022
Not only do glia form close associations with neurons throughout the central nervous system (CNS), but glial cells also interact closely with other glial cells.

Packing problems on generalised regular grid: Levels of abstraction using integer linear programming

open access: yesGraphical Models, 2023
Packing a designated set of shapes on a regular grid is an important class of operations research problems that has been intensively studied for more than six decades. Representing a d-dimensional discrete grid as Zd, we formalise the generalised regular
