As such the CAP has been used to elucidate the diverse mechanisms of injury resulting from a variety of metabolic insults to central nervous white matter, whilst also providing a model with which to assess the benefits of clinically relevant neuroprotective strategies. In addition the technique lends itself to the study of metabolic cell\u2010to\u2010cell signalling that occurs between glial cells and neurones, and to exploring the ability of non\u2010glucose substrates to support axon conduction. Although peripheral nerves are sensitive to metabolic insult and are susceptible to diabetic neuropathy, there is a lack of fundamental information regarding peripheral nerve metabolism. A confounding factor in such studies is the extended duration demanded by the experimental protocol, requiring stable recording for periods of many hours. We describe a method that allows us to record simultaneously the stimulus evoked CAPs from A and C fibres from mouse sciatic nerve, and demonstrate its utility as applied to investigations into fibre sub\u2010type substrate use. Our results suggest that C fibres directly take up and metabolise fructose, whereas A fibre conduction is supported by fructose\u2010derived lactate, implying there exist unique metabolic profiles in neighbouring fibre sub\u2010types present within the same nerve trunk.<\/jats:p><\/jats:sec>","DOI":"10.1113\/jp275680","type":"journal-article","created":{"date-parts":[[2018,3,8]],"date-time":"2018-03-08T15:22:47Z","timestamp":1520522567000},"page":"1795-1812","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Fibre
