function. Binding to the same receptor, oenanthotoxin blocks the chloride channel, allowing excessive excitation to occur. This, blocking GABAergic responses, causes hyperactivity in the neurons, resulting in convulsions, and seizures. Symptoms While oenanthotoxin is extremely dangerous and toxic (LD50 = 0.58 mg/kg for mice), there have been numerous case studies documenting the common symptoms including: convulsions, seizures, nausea, diarrhea, tachycardia, mydriasis, rhabdomyolysis, renal failure, respiratory impairment, and cardiac dysrhythmias.
