Synaptic Connections between a Transplanted Insect Ganglion and Muscles of the Host

When a metathoracic ganglion from one cockroach (Periplaneta americana) is transplanted into the coxa of another cockroach, it innervates only those leg muscles that have been previously denervated. The transplanted ganglion evokes hyperpolarizing synaptic potentials in the host muscles that it innervates. These potentials are correlated with twitching of the host limb.
