 They send branches to several deep nuclear cells and then continue all the way to the
outer layers of the cerebellar cortex, making about 300 synapses with the soma and
dendrites of each Purkinje cell.
 Every single impulse of these climbing fibers cause a single, prolonged (up to 1 second),
type of action potential in each Purkinje cell beginning with a strong spike and followed
by a trail of weakening secondary spikes. This action potential is called the complex
spike.
