Bill Clinton on the brain

I'm currently reading Jeff Hawkins book "On Intelligence" a fantastic tome touting a very different framework for artificial intelligence (more on this later). One interesting note from the book. Apparently, researchers at UCLA and Caltech discovered last year that the brain has specific "Bill Clinton neurons". That is, when you look at a picture of Bill Clinton there are specific cells in your brain that are stimulated by the image. The chart below shows you the details with a picture call out:



Here's the explanation of the chart:

Histograms of responses of a neuron located in the amygdala of a patient during the flash suppression paradigm. We show here the responses of this neuron to two different images of former President Bill Clinton (a black-and-white drawing and a photograph amid other people). For each picture, we show the stimuli projected to the retina (A and D, respectively), the subject’s percept (B and E, respectively), and the neuronal response (C and F, respectively). Left, the image of Clinton is shown monocularly, and a black-and-white pattern is flashed to the other eye, suppressing the percept of Clinton. The neuron increases in activity during the monocular period but reduces its firing rate when Clinton is suppressed. Right, the black-and-white pattern is shown monocularly, and the image of Clinton is flashed to the other eye. The neuron responds only during the flash period when the subject sees Clinton (from, Kreiman G, Fried I, Koch C: Single neuron correlates of subjective vision in the human medial temporal lobe. Proc Natl Acad Sci U S A 99:8378–8383, 2002 [24] © 2002 National Academy of Sciences, U.S.A.).

One report has the following to say about the experiment:

Another finding, revealed in Figure 4, although only suggestive, is really surprising. The neuron responds to the drawing of Clinton’s face but also to very different image of the President, this time in color and in the company of two other persons. This amygdala neuron also responds to a third and different image of Clinton, yet to no other of 50 stimuli, including the pictures of three other presidents or other men. Whether this neuron would respond to all images of Bill Clinton or to other sensory inputs related to him is not known.

So I have a couple of questions: 1) What are the parts of the brain adjecent to these cells and 2) How do modify/delete these cells altogether... I've only got so much space to waste... Or is this a defensive mechanism, something like nerve endings touching a hot object?
