Astrocytes provide the temporal dynamic required for memory formation
Theta oscillations (4-12 Hz) in the hippocampus, driven by synchronous neuronal bursts, are essential for grouping and selecting neuronal ensembles during spatial navigation, memory, and learning 1,2....

An unexpected role for macrophages in motor control - Nature Reviews Neuroscience
A population of macrophages has been found in muscle spindles that release glutamate, activate primary sensory afferents that are part of the stretch reflex, and have a role in regulating locomotion.

Learning-associated astrocyte ensembles regulate memory recall - Nature
A study in mice shows that learning induces c-Fos expression in a subset of astrocytes in the hippocampus, and that ensembles of these learning-associated astrocytes are involved in the recall of memo...
