Summary:
- Astrocytes are a type of glial cell in the brain that play important roles in supporting and regulating neuronal function.
- This article discusses several recent scientific papers that have investigated the detailed ultrastructure and various functions of astrocytes using advanced imaging techniques.
- The findings from these studies provide new insights into the complex morphology and diverse roles of astrocytes in the healthy brain, including their involvement in maintaining the blood-brain barrier, modulating synaptic transmission, and responding to brain injury or disease.
