Psychology
Split-Brain Studies and Lateralization of Function
Quick fact
In split-brain patients, the left hand can draw an object it feels but cannot name it, while the right hand can name the object but cannot draw it — revealing that the left hemisphere handles speech and the right handles spatial skills.
Why this is interesting
Ever wonder why your left hand seems clumsier at writing but better at drawing? The answer lies in a remarkable set of experiments called split-brain studies.
