Activation of different areas in the forebrain evokes different types of goal directed adaptive behaviors. An important component of these different patterns of behavior is the locomotion that brings the animal to or away from a particular location. Here I review the role of projections from forebrain structures to the mesopontine tegmentum of the brainstem where neural mechanisms for initiation of locomotion and regulation of postural muscle tone are located that are activated during locomotor behavior. it is interesting is to understand how signals that converge from the forebrain structures to the mesopontine tegmentum control locomotor behavior, because the mesopontine tegmenturn receives inhibitory efferents from the basal ganglia and excitatory efferents from the limbic-hypothalamic system and the neocortex. Here I hypothesize that the mesopontine tegmenturn has functional gating mechanisms that deter-mine whether the subject will initiate and select volitionally guided or emotionally triggered locomotor behaviors, depending on the behavioral context.
