How Neuron Works

The human brain is possibly one of the most complex systems in the universe. Brain consists with approximately 100 billion, perhaps even more, nerve cells called neurons. Interconnected neurons of the brain are responsible for higher order thinking and complex behaviour. Human brain is an organic electrochemical computer as neurons exploit chemical reaction to generate electricity. 

Structure of Neuron

Electrochemical nature of neurons gives to rise up our actions, our modes and our behaviour. When neuron is excited by external/internal stimuli, it transfer electro-chemical impulses incoming from the dendrites along the axon and onto the next neuron.
