As the control center for the body, it’s essential that the brain is protected from harm. One such shielding mechanism is the organ’s blood-brain barrier, a highly selective filter that acts to keep potentially toxic substances out and thus help preserve the brain’s delicate tissues and chemical balance. But because this barrier is so good at its job, it unfortunately means that if something goes wrong in the brain, it’s incredibly tricky to get therapeutic substances inside to reach target areas.
