Differences between socially isolated vs. group housed mice in physical activity parameters in 24 h and divided by light (inactive phase) and dark (active phase) cycles. Mean ± CI₉₅. Line graphs show physical activity parameters behaviour in 24 h, displaying data every 2 h. The different background colours separate light from dark cycle. Column graphs represent the total sum of count or sum separated by cycle. The statistical differences found in full cycle were the result of changes in physical activity pattern in the light cycle. Unpaired t-student test or Mann-Whitney (for non-parametric data), n = 9–10/group, * p < 0.05.
