Figure 1.

EEG power shown as hourly averages from 12 h before until seven days after ischaemia (A), and five minute averages from two hours before until 12 h after ischaemia (B), in the ischaemia-vehicle, -low dose and -high dose groups, where peptide infusion was started 90 min after the end of ischaemia (the start of infusions is shown by the red arrow). Following the onset of occlusion, EEG power is rapidly suppressed in all three groups. A secondary rise in EEG power was seen in all groups, although this was significantly greater between 2–12 h in the ischaemia-low and -high dose groups. This was followed by a reduction in EEG power to below baseline levels, which persisted at day seven. Data are mean ± SEM. * p < 0.05.
