🧠 **Astrocytes Revealed as Brain's Supervisors, Not Just Support Cells**
* New research published in Science in 2025 indicates that astrocytes, previously thought to be mere support cells for neurons, act as supervisors that tune brain circuits and control overall brain states (e.g., alertness, mood). Experiments in mice, zebra fish, and fruit flies highlight their crucial role in neuromodulation.

⚡ **Astrocytes Control Behavioral State Switches**
* Studies demonstrate that astrocytes play a key role in sudden behavioral changes. For instance, in zebra fish, astrocytes release ATP (converted to adenosine) to suppress swimming neurons, leading to a "giving up" behavior when faced with a futile task. This suggests astrocytes are integral to switching brain states.

💡 **Evolutionarily Conserved Mechanism for Brain Function**
* Parallel findings across fruit flies, zebra fish, and mice reveal an evolutionarily conserved pathway where astrocytes, triggered by neuromodulators like norepinephrine, release molecules that significantly affect neural circuits. This challenges previous models of brain function that solely focused on neurons.
