5 neurons, voltages are reported by angulare velocities of the trasparent circles (yellow=axon, blue=soma); press "0" to reset voltage to -70 mV; press "5" to apply the matrix with the weights of the synapses (it's in the script of the orange laser); press 4 to stimulate neurons (by yellow laser, control its script to regulate); use graphics (angular velocity/time) to see the voltage variation in soma and action potential in axon
