TL;DR: Sommer et al. as mentioned in this paper conducted a meta-analysis on sex differences in language lateralization measured with functional imaging techniques and found that the effect sizes of two studies they suggested were significantly larger than the effect of listening to stories.
Abstract: Sir,
In their Letter to the Editor, Kitazawa and Kansaku responded to our meta-analysis on sex differences in language lateralization measured with functional imaging techniques (Sommer et al , 2004) Though Kitazawa and Kansaku gave an interesting interpretation of the data, we do not agree with the alternative calculation of the effect sizes of two studies they suggested
Kitazawa and Kansaku hypothesized that sex differences in language lateralization may be present only when subjects listen to stories, since two studies (Kansaku et al , 2000; Philips et al …

TL;DR: Three patients, men aged 50 and 32 and a woman aged 30 years, presented with bizarre somatic symptoms, i.e. that are anatomically and physiologically impossible, that occur frequently in patients with schizophrenia.
Abstract: Three patients, men aged 50 and 32 and a woman aged 30 years, presented with bizarre somatic symptoms, i.e. that are anatomically and physiologically impossible. The first patient, for instance, thought that he could only walk while holding his forehead back with his hand; the woman thought that the skin of her neck and back was disconnected from the underlying tissues. The patients were preoccupied with their complaints and could not be convinced that there was no organic substrate for their symptoms. The presented patients had coenesthetic symptoms of schizophrenia: disturbances in the awareness of their bodily integrity. These symptoms occur frequently in patients with schizophrenia, but have not received much attention in medical literature. The patient's visit to a somatic or general physician is a good opportunity to refer him or her for adequate psychiatric treatment.

TL;DR: The activation pattern of fMRI and PET studies, they argue, is composed of language components, but also of non-specific cerebral activity, especially when the control task consists of passive rest.
Abstract: In response to our meta-analysis on sex differences in language lateralization (Sommer et al ., 2004), Ortigue and colleagues point out the limited time resolution of functional MRI (fMRI), PET and echo Doppler as a possible cause for failing to find a significant sex difference in the meta-analysis. The activation pattern of fMRI and PET studies, they argue, is composed of language components, but also of non-specific cerebral activity, especially when the control task consists of passive rest.
Ortigue and colleagues explain that the functionally relevant time for language is between 170 …
