👉 The eeg fluid, or cerebrospinal fluid (CSF), is a clear, colorless liquid that surrounds and protects the brain and spinal cord. It acts as a cushion, absorbing shocks and reducing friction between these vital organs during movement. CSF also plays a crucial role in maintaining a stable chemical environment around the nervous system by regulating temperature, pH, and nutrient levels. Additionally, it helps remove waste products from the brain, ensuring optimal function and health.
