Question #1 - Corrections     Iran is Persion, not Arabic
Question #2 - Croatian Girl Follow Up     Hi, I'm probably only and therefore biggest fan of Skeptics guide here in Croatia so when hearing you mentioning a case of 12 year old girl waking up from coma and speaking fluent German, naturally I wanted to clarify some things (because I actually find this case interesting). Not for its mystical side as preferred in the media but as a medical case. This news broke out in newspapers 24sata which can be compared to English newspaper The Sun - obviously not quality journalism. But surprisingly they actually interviewed doctors from Split hospital that were assigned to the case. It's actually a 13 years old girl which was hospitalized for blood poisoning. Soon after she was hospitalized she went into coma (my guess is she went into a septic shock). Now it's not clear how long was she in the coma but she woke up about 2 weeks ago speaking only German. It is true she learned German in primary school for 2 or 3 years. Croatian is Slavic language but it shares probably around 10% of words with German. Mostly because Croatia was part of the Habsburg monarchy (1526–1804) and Austro-Hungarian monarchy afterwards. Now the interesting part is that after she woke up from the coma she could speak German a lot more fluently than before and not a word in Croatian. My guess is that Sepsis caused a brain damage in left temporal lobe. Probably mostly in Broca's Area, thus disabling her in speaking Croatian but not damaging her knowledge of German language. At that point her brain probably switched to best alternative and her passive knowledge of German sprang to life. Without possibility to fall back to Croatian vocabulary there is no dilemma in which words to choose and how to use them so her German must have sounded a lot better to doctors and her parents. In my opinion the most unsettling thing about this story is not mystical nonsense around it but a quote from a neuropsychiatrist that was connected to this case. He said “This case is medically unexplainable” - only a day after the whole incident. Seems to me that people like him should not be even remotely connected to science. If he is capable of abandoning any rational explanation only a day after girl woke up. I could understand if he spent 50 years researching on that particular case and/or related cases and then states he can’t explain it. But his reckless statement made this story a mockery of journalism and his career instead of interesting medical case what it probably is. What do you think about the whole case and possible explanations? Could Human brain adapt so quickly to make my explanation possible? Best regards, Ivan Osman PS: sorry for my awful English.

Segment:   Quote of the Week     
Quote of the Week     For a scientist must indeed be freely imaginative and yet skeptical, creative and yet a critic. There is a sense in which he must be free, but another in which his thought must be very precisely regimented; there is poetry in science, but also a lot of bookkeeping. — Sir Peter B. Medawar
