Hippocampal cells were grown in Petri dishes in the presence of either 10 mg/mL Shilajit or the formulation of Brain Up-10 [30] plus vitamins of the B complex. In the control, cells were grown in culture medium without Shilajit or the formulation. Mean of 5 determinations ( ) (significance of differences with respect to control, ** ).
