Nonlinear Gap Junctions Enable Long-Distance Propagation of Pulsating Calcium Waves in Astrocyte Networks
A new paradigm has recently emerged in brain science whereby communications between glial cells and neuron-glia interactions should be considered together with neurons and their networks to understand higher brain functions. In particular, astrocytes, the main type of glial cells in the cortex, have been shown to communicate with neurons and with each other. They are thought to form a gap-junct...
متن کاملOn the determinants of calcium wave propagation distance in astrocyte networks: nonlinear gap junctions and oscillatory modes
A new paradigm has recently emerged in brain science whereby glial cells should be considered on a par with neurons to understand higher brain functions. In particular, astrocytes, the main type of glial cells in the cortex, are thought to form a gap-junction-coupled syncytium supporting cell-cell communication via propagating calcium (Ca) waves. The propagation properties of these waves and th...
متن کاملSparse short-distance connections enhance calcium wave propagation in a 3D model of astrocyte networks
Traditionally, astrocytes have been considered to couple via gap-junctions into a syncytium with only rudimentary spatial organization. However, this view is challenged by growing experimental evidence that astrocytes organize as a proper gap-junction mediated network with more complex region-dependent properties. On the other hand, the propagation range of intercellular calcium waves (ICW) wit...

induced contrasts was varied between trials and the participant was required to judge the angle on each trial (Figure 1). Hence, the task mandated a fine-scaled decision which required detail to be extracted – detail at such a fine scale that it may only be present in V1 due to its small receptive fields – and might therefore have induced correlated V1 activity. A hypothesis put forth by Crick ...
متن کاملTopology drives calcium wave propagation in 3D astrocyte networks
Glial cells are non-neuronal cells that constitute the majority of cells in the human brain and significantly modulate information processing via permanent cross-talk with the neurons. Astrocytes are also themselves inter-connected as networks and communicate via chemical wave propagation. How astrocyte wave propagation depends on the local properties of the astrocyte networks is however unknow...
