Fig 2. Intraperitoneal injection of NLP had no effect on physical activity during both dark and light phase.

No significant change in average O₂ consumption and CO₂ production was observed during the dark and light phase (a & b). The locomotor activity (c-f); Ambulatory (X-AMB, refers to beam breaks in X axis) was higher in NLP treated group, but no change in horizontal (Y-TOT), vertical (Z-TOT) movements or in total activity was observed after the treatment. The activity is presented as beam breaks/12 h. Data are represented as mean ± SEM with n = 6 rats/group.
