Model of the MB. The PNs send afferents into the calyx of the MB, where they make connections to KCs. KCs project to ENs with plastic connections wij. Initially, the weights of these connections are strongest to the “retraction” group. The MB outputs can be divided into two groups of output neurons that compete with each other via inhibitory connections. The extension group activates the proboscis and the retraction group either retracts it if it is extended or holds it in the retracted state.
