There are a number of neurones involved in modifying the neuronal signals in the exrtapyramidal tract. These include the neurones then relay within nuclei which include the red nucleus, the substantia nigra, the caudate nucleus, the subthalamic nuclei and the olive in the [[Hindbrain - Anatomy & Physiology#Medulla Oblongata|medulla oblongata]]. The [[Sensory_Pathways_-_Anatomy_%26_Physiology#Ascending_Reticular_Formation|reticular formation]] is also involved in the extrapyramidal pathway. Neurones that relay in the red nucleus and reticular formation relay directly onto lower motor neurons whilst others relay to other nuclei. The main descending motor tracts from the red nucleus and the reticular formation are the '''rubrospinal tracts''', the '''reticospinal tract''', the vestibulospinal tract''' and the '''tectospinal tract'''. The rubrospinal tract is the important in carnivores and ungulates as it modulates pattern generators in the [[Spinal Cord - Anatomy & Physiology|spinal cord]].
