The changes in membrane potential (Up) and extracellular glucose concentration (Down) with variable glucose level during neuronal activation. a $[\text{Glucose}](0)=6\text{mM}$; b $[\text{Glucose}](0)=8\text{mM}$; c $[\text{Glucose}](0)=10\text{mM}$; d $[\text{Glucose}](0)=12\text{mM}$; e $[\text{Glucose}](0)=16\text{mM}$; f $[\text{Glucose}](0)=20\text{mM}$. The initial value of glucose concentration, $[\text{Glucose}]\left(0\right)$, is shown as a red dotted line in each case
