The Gate Theory of Pain Revisited: Modeling Different Pain Conditions with a Parsimonious Neurocomputational Model

Figure 9

Modeling breakthrough pain: after 50 iterations with standard training epochs, an intense nociceptive stimulus is input to the gate. Initially, wind-down pain (yellow ribbon) takes place concomitantly with a mild episode of dysesthesia (cyan ribbon). After a period in which pain seems to be relieved, pain is again installed as in breakthrough pain.
