Why Is Your Brain Constantly Eating Itself?

💡 The Answer

• The brain undergoes a process called phagocytosis, where cells consume smaller cells or molecules.
• This self-cleaning mechanism removes damaged components and keeps neural pathways functioning efficiently.
• Far from being harmful, phagocytosis actively preserves grey matter and supports brain health.
• Specialised brain cells called microglia are primarily responsible for carrying out this process.
