**6. Glucose error commission depression effect: Cue to an overlapping bridge of neural error systems, memory and glucose metabolism?**

Our data and those of other authors show strong negative relations between glycemia and error commission. Whether this is due to the effect of glucose on memory or neural systems of error commission, is what is not exactly clear (see figure 2). There are no precise borders between the brain regions responsible for memory and error commission. Therefore, it is possible that the effect of glucose on error commission could be the resultant effect on the chief brain regions for memory function. Neural systems (or regions) of memory implicated in error commission have been linked to brain regions also involved in some aspects of memory function [115-117]. The brain systems concerned with error commission are referred to the error monitoring and processing system. The major regions of the brain concerned with error commission are the anterior cingulate cortex, basal ganglia, prefrontal cortex. These brain regions (especially the prefrontal cortex) are also implicated in memory function [45, 115, 117].
