What does tetrathylammonium do to a neuron?

Tetraethylammonium (TEA) is a quaternary ammonium compound that primarily acts as a blocker of voltage-gated potassium channels in neurons. By inhibiting these channels, TEA prolongs the action potential duration and enhances neuronal excitability. This disruption can lead to increased neurotransmitter release and altered neuronal signaling, impacting synaptic transmission and overall neuronal function.
