Research suggests that calcium signals in certain brain cells, possibly microglia, may play a role in regulating anxiety and compulsive behaviors. Some studies indicate that these calcium signals could potentially turn anxiety on and off, while others discuss the involvement of different brain cells, such as astrocytes, in behavioral regulation and neuroinflammation. The relationship between calcium signaling, brain immune cells, and anxiety is still being explored, with some outlets mentioning microglia and others discussing astrocytes.
