M more specialized f less lateralized + have language centers on both sides of brain; advantageous = recover from stoke better. 4- brain connectivity = dti study measures water flow across brain. M: connections in same hemisphere = accounts for better musculature/motor skills. F: more cross-hemisphere connections = for better analytical, verbal, intuitive abilities. M better at manipulating objects, constructing 3d forms, mental map complex figures. F tend to speak + write earlier and have superior verbal abilities in early school years.
