Uranium etc travel nerves from nose to brain: nickel, thallium...
- * Uranium travels nerves from nose to brain.
31 July 2009
A study with rats suggests that radioactive uranium inhaled by
soldiers on the battlefield and by workers in factories may bypass
the brain's protective barrier by following nerves from the nose
directly to the brain. This study provides yet another example of
how some substances can use the olfactory system to bypass the
brain's protective blood barrier and go directly to the brain.
Titanium nanoparticles and the metals manganese, nickel, and
thallium use the same route.
*Role of the olfactory receptor neurons in the direct transport of
inhaled uranium to the rat brain.*
