  • Values are given as the mean ± SEM, unless otherwise indicated. Statistical analysis did not reveal significant difference between Ctrl and Tin groups in all parameters presented in the table. Similarly, no difference was found between dMGB and vMGB neurons. Depth, MGB neurons depth from a slice surface (μm).
