O-c-D

"It has been theorized that a miscommunication between the orbital-frontal cortex, the caudate nucleus, and the thalamus may be a factor in the explanation of OCD. The orbitofrontal cortex (OFC) is the first part of the brain to notice whether or not something is amiss. When the OFC notices that something is wrong, it sends an initial “worry signal” to the thalamus. When the thalamus receives this signal, it in turn sends signals back to the OFC to interpret the worrying event. The caudate nucleus lies between the OFC and the thalamus and it prevents the initial worry signal from being sent back to the thalamus after it has already been received. However, it is suggested that in those with OCD, the caudate nucleus does not function properly, and therefore does not prevent this initial signal from recurring. This causes the thalamus to become hyperactive and creates a virtually never-ending loop of worry signals being sent back and forth between the OFC and the thalamus. The OFC responds by increasing anxiety and engaging in compulsive behaviors in an attempt to relieve this apprehension" - Wikipedia

No Cellphones on Plane

WASHINGTON (AP) -- A government agency on Tuesday said it will keep a rule in place that requires cell phones to be turned off during airline flights.

The reasoning behind the decision was technical. But the avalanche of comments the Federal Communications Commission has logged from airline travelers have been nothing short of visceral.
