From: Multifunctional central pattern generator controlling walking and paw shaking
Two mutually inhibitory interneurons, IntE (Extensor Interneuron) and IntF (Flexor Interneuron) produce alternating bursting activity at approximately 1.6 Hz representing walking pattern. A switch to paw shaking is executed by a pulse of excitatory conductance delivered to both cells for 1 second. The paw shake rhythm is represented by a 9 Hz bursting regime. An inhibitory conductance activated for .1 second in IntF causes a large rebound burst and a fast transition back to the walking rhythm.
