    “…Next, to test for other potential mechanisms involved in 3-T(1)AM-induced c-FOS activation in PVN, we evaluated the effect of 3-T(1)AM on the intracellular Ca(2+) concentration and whole-cell currents. The fluorescence-optic measurements showed a significant increase of intracellular Ca(2+) concentration in the three cell lines in the presence of 10 μM 3-T(1)AM. …”
