Fig. 5: Chemical regulated threshold shifts of FON.
A Schematic illustration on the low spiking threshold at resting state (upper) and high spiking threshold (lower) at refraction state of biological neurons (left) and FON (right). G-t curves of a FON in asymmetric solution with different concentration gradient and different biases (upper, −3 V; middle, −5 V; bottom, −10 V): B Inner: 0.1 M KCl+1 mM K3Fe(CN)6; Outer: 0.1 M KCl+10 μM K3Fe(CN)6; C Inner: 0.1 M KCl+1 mM K3Fe(CN)6; Outer: 0.1 M KCl+50 μM K3Fe(CN)6; D Inner: 0.1 M KCl+1 mM K3Fe(CN)6; Outer: 0.1 M KCl+100 μM K3Fe(CN)6.
