The caudate nucleus and putamen, together known as the striatum, are responsible for initiating and controlling the cycles of arm and leg movements while walking. They receive information from the cortex and basal ganglia and send output to the thalamus, which then relays the signal to the motor cortex to initiate movement. The globus pallidus is involved in regulating movement, but not specifically in controlling the cycles of arm and leg movements during walking. The amygdaloid body is involved in emotion and memory, and the claustrum is involved in attention and consciousness, but neither is directly involved in controlling movement.
