Meet Matt Chaney. He's been diagnosed with pseudobulbar affect, a neurological condition which shows up in about one of three people with ALS or Lou Gehrig's disease. The result? Uncontrollable fits of laughter and crying that strike as often as three or four times a day. Watch Matt's episodes from the outside, and from within an fMRI machine, as scientists try to figure out how emotions play out in the human brain.

Being a neurologist in the era of fMRI scanners must feel like being a kid in a candy shop. What's going in there while we're, say, shopping? How about reading? Watching campaign ads? Now that we have a way to take real-time images of the brain at work, the scientific possibilities are endless.

People with pseudobulbar affect -- a neurological condition common in patients with Lou Gehrig's disease - have overwhelming emotions at inappropriate times. Scientists at UC San Francisco believe that by putting these people into MRI scans, they can learn more about how emotions are created and controlled in the human brain - and what happens when those systems break down.
Matt Chaney, like others with Pseudobulbar Affect, suffers from amyotrophic lateral sclerosis (ALS), or "Lou Gehrig's" disease. Since his diagnosis, Chaney has raised about half a million dollars for the ALS Association.
