(BBC) — Ariel Sharon, the former Israeli prime minister who has been in a coma for seven years, has shown significant signs of brain activity, doctors say.
A team of Israeli and American scientists say new tests showed he responded to external stimuli.
The activity increased when he was being shown pictures of his family and played a recording of his son’s voice.
The 84-year-old has been in a coma since 2006, when he suffered a massive stroke.
