Changes in single and multiple synaptic boutons

	Synapses formed by
	Single synaptic boutons	Multiple synaptic boutons
Sham–MC	16.56  ± 0.92	1.58  ± 0.37
Sham–AC	19.09  ± 1.29	2.87  ± 0.42**
Lesion–MC	19.30  ± 0.94	2.70  ± 0.24
Lesion–AC	23.64  ± 1.06*,**	2.92  ± 0.48

Data are 10³ layer V synapses per neuron (synaptic density/neuronal density).

*p < 0.005 significantly different from sham of the same training condition.

**p < 0.05 significantly different from motor control of the same lesion condition.
