A short circuit is a low-resistance connection between two points of an electrical circuit that are at different voltages.

Brain – the main switch of our body, controls all parts of our body through the wired network (nerves). Brain cells send signals as electrical impulses to the periphery for every action. Any spark or voltage fluctuations or interruptions or flickering (abnormal brain signals or activity) can cause short circuit (i.e., tic / twitch / spasm / seizure / convulsions / epilepsy complaints) in connections and communications – seizure disorders. It is just like an error code transmitted in brain cells (neurons). It can also go for fuse off the brain (death) when there is persistent spark or flickering (sustained twitching or seizure / status epilepticus) when care is not taken / given properly to control it.
