Brain and body weight after 7-day ECS treatments during postnatal development

Treatment period	Group (n)	At time of sacrifice		Δ body weight for 7 days^a	Brain/body weight ratio x 100
Treatment period	Group (n)	Brain weight (g)	Body weight (g)	Δ body weight for 7 days^a	Brain/body weight ratio x 100

P1-7	Sham (8)	0.70 ± 0.019	16.06 ± 0.82	9.38 ± 0.76	4.41 ± 0.24
P1-7	ECS (8)	0.67 ± 0.019	13.86 ± 1.42	7.08 ± 1.33	5.10 ± 0.44

P7-13	Sham (9)	1.06 ± 0.019	25.62 ± 1.21	12.88 ± 1.36	4.20 ± 0.21
P7-13	ECS (9)	1.08 ± 0.021	24.09 ± 0.79	9.68 ± 1.33	4.50 ± 0.17

P14-20	Sham (11)	1.26 ± 0.031	39.32 ± 3.11	14.10 ± 1.75	3.35 ± 0.20
P14-20	ECS (11)	1.27 ± 0.021	37.61 ± 2.56	9.75 ± 1.62	3.51 ± 0.18

Values are expressed as mean ± SEM. There was no significant difference between ECS treated and sham treated animals for any parameters.

Δ Body weight = Body weight at time of sacrifice minus body weight at time of the first ECS (or sham) treatment.
