*2.3. E*ff*ect of Nimodipine at 10 or 20* μ*M Dissolved in Varying DMSO Concentrations*

L-type calcium channel blockage with nimodipine at either 10 or 20 μM dissolved in 0.1 or 1.0 Vol.% DMSO, respectively, did not show significant neuroprotection (Figure 3).

**Figure 3.** Slices undergoing OGD received nimodipine at either 10 or 20 μM dissolved in 0.1 or 1.0 Vol.% DMSO. No significant differences in cell damage were observed at 72 h after OGD (OGD *n* = 96; dissolved in 0.1 Vol.% DMSO: 10μM nimodipine *n* = 77, 20 μM nimodipine *n* = 64; dissolved in 1.0 Vol.% DMSO: 10 μM nimodipine *n* = 30, 20 μM nimodipine *n* = 25).
