Relative neuron size was determined in fluorescent Nissl-stained brain sections by threshold densitometry. Sections from the ipsilateral and contralateral hemispheres were matched for position in mice that were subjected to 2 hours MCAO, MCAO and 2 hours reperfusion or sham surgery. The data are an index of the average number of pixels in a neuron for each condition. * P < 0.01 for +/+ as compared to -/- of the same condition.
