Investigations into the analysis of the rate of decay of the compound action potentials recorded from the rat sciatic nerve after death: significance for the prediction of the post-mortem period.
There have been a number of papers that have reported the investigations of electrical stimulation of muscle groups in order to determine the post-mortem period. To the authors knowledge, no techniques have been described that analyse the compound action potentials (CAP) of various nerve fibre groups after death. This paper reports the monitoring of both the amplitude and latency changes of the CAP recorded from a stimulated rat sciatic nerve after death. Initial results suggest that the method my be useful in determining the early post-mortem period within 1 or 2 h after death. It may also be of use in measuring nerve conduction delay in various pathological conditions that can affect the neural network; for example diabetes.
