An individual with this neurological disorder has full sensation in the rogue hand, but is unable to control its movements, and does not feel that it is a part of their body.  The hand becomes personified, as if it has a will of its own, and its owner will usually deny ownership of the limb.</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.damninteresting.com/?p=203">The symptoms are brought on by an injury to the brain, such as head trauma, stroke, tumor, or infection, but it can also be a side effect of a certain kind of brain surgery where the patient has the two lobes of the brain separated to relieve severe epilepsy.</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.damninteresting.com/?p=203">the alien hand may also engage in complex purposeful behavior, such as compulsive manipulation of tools, undoing buttons, or tearing clothes.  Sometimes the sufferer is completely unaware of what the hand is doing until it is brought to his or her attention, or until they happen to see it themselves.</blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/626A1877-6276-40EC-98DC-220A144CD445/blog/" title="blog or email this clip"><img src="http://content8.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
