Fundamentals of the Nervous System and Nervous Tissue
... Microglia (mi-krogle-ah) are small ovoid cells with relatively long “thorny” processes (Figure 11.3b). Their processes touch nearby neurons, monitoring their health, and when they sense that certain neurons are injured or in other trouble, the microglia migrate toward them. Where invading microorga ...

Learning place cells, grid cells and invariances: A unifying model
... The cellular and network mechanisms that give rise to each of these firing patterns are subject to extensive experimental and theoretical research. Several computational models have been suggested to explain the emergence of grid cells [9–21], place cells [11, 22–27] and head direction cells [11, 28 ...
