Neural Circuits: the brain’s road system




                                                                              Some actions involve lots of


                                                                              neurons firing all at the same time.




                                                                              This is called a neural circuit.















        It’s a bit like road system


        joining different parts of a city


        – but instead, the roads are


        electrical signals and instead



        of linking parts of a city, they                                       Each time groups of neurons fire


        link neurons.                                                          together, the circuit gets stronger
                                                                               and faster.
