Thanks to large scale neuroimaging initiatives like the human connectome project, we now have a wiring diagram of the healthy human brain. This wiring diagram helps us see how brain regions are connected, both structurally and functionally. An important question is how this wiring diagram, based on healthy brains, can be used to help patients with brain disease. Here, I provide two examples. First, I show how this wiring diagram can be used to understand and localize symptoms caused by focal brain lesions. Because symptoms can come from brain regions connected to the lesion location, not just the lesion location itself, a map of human brain connectivity is critical for linking symptoms to specific brain regions. I will show application of this concept towards understanding lesion-induced hallucinations, delusions, involuntary movements, and disruptions in consciousness. Second, I will show how the normative human connectome can be used to better understand and guide brain stimulation therapies. Because therapeutic benefit from brain stimulation can come from connected brain areas, not just the site of stimulation, a map of human brain connectivity can help identify the ideal spot to stimulate. I will show application of this concept for deep brain stimulation for Parkinson’s disease and transcranial magnetic stimulation for depression.
