Values are mean number (±s.e.m.) of FLI neurons/section. a, indicates comparison between oxygenated and anoxic conditions for classic, low Ca2+−high Mg2+ CSF and middle VMS lesion; b, indicates comparison between classic and low Ca2+−high Mg2+ CSF oxygenated conditions; c, indicates comparison between classic and low Ca2+−high Mg2+ CSF anoxic conditions; d, indicates comparison between classic-CSF and middle VMS lesion in oxygenated conditions; e, indicates comparison between low Ca2+−high Mg2+ CSF and middle VMS lesion in oxygenated conditions; f, indicates comparison between classic CSF and middle VMS lesion in anoxic conditions; g, indicates comparison between low Ca2+−high Mg2+ CSF and middle VMS lesion in anoxic conditions. n.s., not significant.
