Briefly, coronal brain sections (100 mm)were cut with a vibratome, postfixed with 4% glutaraldehydein 0.1 mmol/L cacodylate buffer (pH 7.4) for 1 h, andthen with 1% osmium tetroxide in 0.1 mmol/L cacodylatebuffer for 2 h. After rinsing with distilled water, the brainsections were treated with 1% aqueous uranyl acetateovernight, dehydrated in an ascending series of ethanolsto 100%, followed by dry acetone, and then embedded inDurcupan ACM. Ultrathin sections (0.1 mm) were cut andstained with 3% lead citrate and subsequently examinedwith a Zeiss transmission electron microscope (Zeiss Inc.,Thornwood, NY, USA).
