✦ Synopsis
Neural regeneration in the escape viates markedly from normal; these animals reestabcircuit of the first-instar cockroach is described using lish near normal escape behavior. In a few cases, rebehavioral analysis, electrophysiology, intracellular generating afferents remain within the cercus or bystaining, and electron microscopy. Each of the two pass the cercal glomerulus, and thereby fail to re-form filiform hairs on each of the animal's cerci is innersynapses with GIs; these animals continue to exhibit vated by a single sensory neuron, which specifically perturbed escape behavior. We conclude that in most synapses with a set of giant interneurons (GIs) in the cases, specific synapses are reestablished and approterminal ganglion. These trigger a directed escape priate escape behavior is restored. This regeneration run. Severing the sensory axons causes them to degensystem therefore provides a tractable model for the erate and perturbs escape behavior, which is restored establishment of synaptic specificity in a simple to near normal after 4-6 days. Within this time, afferneuronal circuit.
