Neural Firing: the brain’s postal system






        This system is a bit like a letter in the post – information starts in


        one place and travels to another.








        When a neuron fires an electrical signal,



        it travels down the trunk of the neuron


        and releases special brain chemicals.








         These brain chemicals and the ‘branches’



         of the neuron help the signal to travel


         across a gap (called the synapse) to the


         next neuron.
