- In individuals with multiple sclerosis, there is a significant decrease in their ability to perform dual tasks (performing a motor and cognitive task simultaneously) 
- Neuroimaging studies of individuals with MS saw a significant increase in activity only within the SMA as the participants performed an assigned task 
- This suggests that the SMA is responsible for dual task performance, although further research is needed to strengthen this connection

Smith College

- Used for the preparation/organization of movements
- Ex. For individuals that have damage to the SMA, they cannot move outside of automatic reflexes (that are involuntary)
