Tetrаethylаmmоnium (TEA) is а pоtent neurоtoxin that results in death from respiratory failure within 10 to 30 minutes. When a neuron is incubated with TEA, researchers observed that action potentials could be generated, but the membrane potential remained positive and never returned to the resting membrane potential. What channel is TEA likely acting on?
