Decreasing neuronal excitability has a sedative effect Presynaptic Neuron Post Synaptic Neuron Synaptic Vesicle GABA binds to the GABA A receptor in between the alpha and beta subunits. This causes the chloride channel to open causing hyper-polarization in the post synaptic neuron suppressing signalling. Thiocolchicoside binds to an allosteric site of the GABA A receptor. This also causes the chloride channel to open more frequently causing hyper-polarization in the post synaptic neuron further suppressing signalling. Cytosol Cytosol Synapse
