The pre-SMA (pre-supplementary motor area) is thought to be involved in the planning and initiation of voluntary movement and may serve as a "bridge" between these two processes. The SMA (supplementary motor area) is also involved in motor planning and initiation but is not specifically mentioned as a "bridge" in this context. The red nucleus is involved in motor control, specifically in the control of arm movements, but is not involved in the planning and initiation of movement. The putamen is part of the basal ganglia and is involved in motor control and learning, but is not specifically involved in the planning and initiation of movement.
