It sounds like you are referring to **astrocytes**, a type of glial cell found in the central nervous system. Astrocytes play a crucial role in supporting neurons by:
1. **Supplying Energy**: They assist in the metabolism of neurotransmitters and can store and release glucose in the brain, providing energy to neurons.
2. **Maintaining Electrolyte Balance**: Astrocytes help regulate ion concentrations in the extracellular space, particularly potassium ions, which is essential for maintaining the proper functioning of neurons.
3. **Blood-Brain Barrier (BBB)**: They contribute to the formation and maintenance of the blood-brain barrier by interacting with endothelial cells of capillaries, which helps protect the brain from potentially harmful substances in the blood.
4. **Supporting Neurotransmitter Recycling**: Astrocytes take up excess neurotransmitters released during synaptic transmission and recycle them, which is important for maintaining synaptic function.
Overall, astrocytes play integral roles in neuronal health, communication, and the overall environment of the brain.
