Myelin integrity genetically determined in many brain areas important for intelligence and better integrity= more intelligence
Chemical: move away from other ions
Any stimulus that increases outflow of + ions or inflow of - ions
Often involves gated Na channels opening and Na+ inflowing creating more + charge inside
Blocks Na+ channels= paralysis
Shift opening and closing of Na+ channels = scrambled signals
Blocks K+ channels= prolonged action potentials
