Hypoglossal motoneurons are a type of motor neuron located in the hypoglossal nucleus of the brainstem. These neurons are responsible for controlling the muscles of the tongue, allowing for movements such as licking, chewing, swallowing, and speaking. Research in this area focuses on understanding the neural circuitry and physiology of hypoglossal motoneurons, as well as their role in various neurological disorders such as sleep apnea, dysphagia, and speech impairments. By studying hypoglossal motoneurons, researchers hope to develop new treatments and therapies for these conditions.
