the infarct occurred 16 hrs ago, from 12-24hrs after the infarct there will be Red Neurons.
CNS Hemorrhage/ damage
1) 12-48 Hrs = red neurons
2) 1-3 days = neutrophils (liquefactive necrosis)
3) 3-5 = macrophages (microglia)
4) 1-2 weeks = Reacitve gliosis (+ vascular proliferation)
5) more than 2 weeks = Glial scar
(note: the pathogenesis is similar to MI and its scar formation; however, the time course for CNS is just faster)
