Rapid postmortem decrease in the ectocellular acetylcholinesterase activity in rat striatum as assessed by in vivo microspectrophotometry.

The acetylcholinesterase (AChE) activity in striatum rat was determined before and shortly after death using the in vivo microspectrophotometric method. This technique allowed us to monitor the Ellman colorimetric reaction directly inside the brain using an optical probe implanted in a live animal a... View More
