Aniso	128.0 ± 11.1***	104.8 ± 3.6***
Cyclo	146.2 ± 22.0**	107.8 ± 3.5***
LFS at 30 s	130.2 ± 18.8***	99.8 ± 5.7***
LFS at 15 min	159.2 ± 13.8***	106.6 ± 4.6***
LFS at 15 min (OA)	275.3 ± 42.9	139.8 ± 14.6
LFS at 15 min (8-Br)	259.5 ± 35.8	146.4 ± 7.1
LFS at 35 min	271.9 ± 48.2	146.8 ± 4.5

Normalized changes are calculated for each condition, typically around 40∼45 min after TBP. The numbers are mean ± SEM.
