What is Proprioception?

Neuroscience and Neurology CategoryEveryone learns in school about the five senses: vision (sight), audition (sound), olfaction (smell), taction (touch), and gustation (taste). These senses are responsible for our interaction with the external world. Additionally, we have several senses that are responsible for our internal functioning. One of the most important internal senses is called proprioception, or position sense.

Overall, an estimated 1 in 5 Americans will experience depression sometime in their lives, equating to a large number of children with depressed parents. Many studies have focused on the treatment of depression in both adults and children and adolescents, but few focus on its prevention.
