Final answer:
Superior colliculus deep brain stimulation is not a used surgical intervention for idiopathic Parkinson's disease as it is not related to motor control functions affected by the disease.
Step-by-step explanation:
Among the listed surgical interventions for the treatment of idiopathic Parkinson's disease, Superior colliculus deep brain stimulation (C) is not used for its invasive treatment. Parkinson's disease primarily involves the degeneration of the dopamine-producing neurons in the substantia nigra pars compacta. Surgical options for Parkinson's, such as Thalamotomy (A), Subthalamic nucleus deep brain stimulation (B), Pallidotomy (D), and Pallidal deep brain stimulation (E), directly or indirectly target the basal ganglia and its connections to manage symptoms. However, Superior colliculus is not typically a target in deep brain stimulation for Parkinson's disease as it is part of the midbrain tectum involved in processing visual information, rather than motor control.
