Table 1.

Changes in cortical current density (µV²/mm⁴) before (pre) and after (post) as well as 15 min after (post15) the aerobic exercise and the art class in the frontal, parietal, and occipital lobes

	Lobe	Pre	Post	Post15
Exercise	frontal	–2.84±0.53	−3.46±0.34**	−3.21±0.35*
	parietal	−2.06±0.58	−2.34±0.48**	−2.18±0.55*
	occipital	−0.57±0.10	−0.82±0.34**	−0.72±0.33*
Art	frontal	−3.00±0.46	−3.04±0.32	−3.03±0.28
	parietal	−2.07±0.60	−2.15±0.44	−2.09±0.48
	occipital	−0.67±0.53	−0.66±0.35	−0.60±0.48

A significant effect from pre to post (p < 0.01) and pre to post15 (p < 0.05) was noticeable after the exercise but not the art class. This effect was independent of lobe. Asterisks mark changes to pre:

^**p < 0.01;

^*p < 0.05.
