Fig. 7From: Conditions for Multi-functionality in a Rhythm Generating Network Inspired by Turtle ScratchingReduced module controlling knee extensor activity. Two interneuron units form a half-center oscillator, linked by mutual inhibition (thick solid lines). Each unit recruits a corresponding hip MN (thin solid lines) and supplies a hybrid excitatory and inhibitory input to KE (dot dashed lines with squares), with a single corresponding synaptic conductance variableBack to article page
