(A) Timeline for hypoxia experiments. The arrow labeled hsd indicates the approximate time after the initiation of hypoxia at which the hsd occurred. The times (in min) shown in brackets indicate the time remaining before reoxygenation. (B) Timeline for hypoxia experiments with 0% Ca2+. Normal ACSF is replaced with Ca2+-free ACSF at 10 min following the start of the experiment (as indicated by the grey shaded area). This is continued for 20 min before the start of hypoxia, during hypoxia and for 10 min following reoxygenation.
