Number and density of VAChT⁺ terminals on the soma and dendrites of SMAΔ7 and wild-type mice at P13

Measurement	WT L1–L2	SMAΔ7 L1–L2	WT L5–L6	SMAΔ7 L5–L6
Somatic VAChT puncta number	4.4 ± 0.4	4.7 ± 0.4	2.7 ± 0.27	3.3 ± 0.3
Somatic VAChT puncta density	0.017 ± 0.001	0.026 ± 0.002*	0.013 ± 0.001	0.017 ± 0.001
Dendritic VAChT puncta number	4.2 ± 0.5	7.1 ± 0.8*	4.7 ± 0.5	5.1 ± 0.4
Dendritic VAChT puncta density	0.059 ± 0.006	0.129 ± 0.01*	0.076 ± 0.008	0.095 ± 0.008

Somatic densities are expressed as number of puncta/square micrometer of somatic area and dendritic densities are number of puncta/linear micrometer of dendrite. VAChT, vesicular acetylcholine transporter.

^*P < 0.001, Kruskal-Wallis test comparing SMAΔ7 toWT in the L1/2 segments.
