- Scientists study how the brain fights damage from calcium.
- High calcium can slowly damage many brain cells.
- A protein called GLO1 helps remove toxic chemical waste.
- GLO1 levels rise when calcium becomes too high.
- Later, GLO1 activity falls in older animals.
- They also study a calcium channel called RyR2.
- RyR2 can leak calcium like an open faucet in cells.
- Animals with a constant leak had worse memory in tests.
