Denne nevner at både for høyt og for lavt blodsukker er sakdelig for nervesystemet. Hele studien er ikke publisert enda, men når den kommer blir det interessant å se hvor høyt blodsukkeret er før det begynner å påvirke nervesystemet. Den nevner at alt mellom 2,8 – 5,6 nmol/L er ok.

The effects of glucose on the nerve action potential (NAP) were investigated for concentrations between 0 mmol/l and 55.5 mmol/l in an in vitro system using rat sciatic nerve.

Results: Hypoglycemia produces immediate reductions in NAP amplitude and velocity, while hyperglycemia has the opposite effect in the short term.

Over a 12-hour experiment, the amplitude of the NAP remained stable for glucose concentrations in the range 2.8-5.6 mmol/l, but when the glucose concentration was <2.8 mmol/l or >27.8 mmol/l, the amplitude of the NAP declined.

This study confirms the importance of glucose concentration for nerve function especially during anoxia.
