The trouble is that vagus-nerve stimulation can take a long time to produce its full beneficial effect. According to Dr
Conway, scans taken using a technique called positron-emission tomography show significant changes in brain
activity starting three months after treatment begins. The changes are similar to the improvements seen in
patients who undergo other forms of antidepression treatment. The brain continues to change over the following
21 months. Dr Conway say fuel dispenser s that patients should be told that the antidepressant effects could be slow in coming.
However, Richard Selway of King s College Hospital, London, found that his patients moods improved just weeks
after the implant. Although brain scans are useful in determining the longevity of the treatment, Mr Selway notes
that visible changes in the brain do not necessarily correlate perfectly with changes in mood.
Nobody knows why stimulating the vagus nerve improves the mood of depressed patients, but Mr Selway has a
theory. He believes that the electrical stimulation causes a region in the brain stem called the locus caeruleus
(Latin, ironically, for “blue place� to flood the brain with norepinephrine, a neurotransmitter implicated in
alertness, concentration and motivation—that is, the mood states missing in depressed patients. Whatever the
mechanism, for the depressed a therapy that is relatively safe and long lasting is rare cause for cheer.

and perch upside down. This is a trick that human engineers would like to emulate. But first they have to
understand it.
