A chimeric ligand–gated channel is activated by the ligands that activate both parent channels, which gate it through two distinct mechanisms.

The aim of this study was to compare the physical activity levels of children during fullday and half-day kindergarten. Of the 47 children who participated in this study, 22 (girls = 50%) attended full-day kindergarten and 25 (girls = 40%) attended half-days. Actigraph activity monitors were used to assess physical activity and sedentary behavior of the children. We found that children were more active during full-day kindergarten. The rates of light-intensity physical activity were significantly higher during full-day kindergarten. However, levels of moderate-to-vigorous physical activity (MVPA) were quite low, and efforts to promote MVPA would be beneficial.
