The brief highlights a shift in understanding of fear and memory, illustrating that non-neuronal cells—astrocytes—play active, real-time roles in forming, recalling, and modulating fear responses. This challenges traditional neuron-centric models and underscores the importance of considering glial contributions when interpreting fear-related processes, which may inform a broader, systems-oriented perspective for mental health practice.

These overlooked brain cells may control fear and PTSD
https://www dot sciencedaily dot com/releases/2026/04/260403224508 dot htm
Astrocytes, once thought to be mere brain “support cells,” are now revealed to be key players in fear memory. Researchers found they actively help form, recall, and weaken fear responses by interacting with neurons in real time. Changing astrocyte activity directly altered how strong fear memories became. This breakthrough could lead to entirely new treatments for anxiety-related disorders.
