What advantage is there in having the special sensory organs confined to the head region?

increases the speed of impulse transmission

Explanation: The advantage of having special sensory organs confined to the head region is that it can help us process the impulses into information faster. A lower risk of damage due to the short distance of the nerves is also an advantage of having sensor organs near the head region. However if one gets a head injury it can be dangerous since the injury may damage the sensory organs, and can take a long period of time to fully recover.
