Your Brain Has “Immune Cells” That Can Change Your Personality
Inside your brain are tiny immune cells called microglia.
They don’t just fight infections—they also:
- prune synapses
- shape memory
- influence mood
- affect creativity
- modulate decision-making
New research shows that overactive microglia (often caused by chronic inflammation, poor sleep, or aging) can literally reshape personality traits by altering how neural networks communicate.
