Whoa!! Mercury really is our brain cells' kryptonite ​ ​This is what happens when a neuron comes into direct contact with low concentrations of the neurotoxin. 😱 Mercury ions bind to tubulin molecules of growing neurons, preventing them from linking to each other to form their usual cell supportive structures (microtubules). This causes the neuron to collapse. ​ ​📷: University of Calgary | ScienceAlert
