The study which Professor Kader Karli Oguz, UMRAM researcher Arzu Ceylan Has and a group of scientists from Neurology Department of Hacettepe Hospital carried out on patients of ischemic stroke have been published in the January 2015 issue of Stroke. Editorial of the same issue is also on this article. In this study a consecutive series of patients with ischemic stroke, retrospectively determined clinical and imaging features associated with nonsustained AF (n=126), defined as <30-second-lasting supraventricular tachyarrhythmias with irregular RR interval on 24-hour Holter monitoring, and compared to the patients with persistent/paroxysmal AF (n=239) and no AF (n=246). Leison probability distribution map of each patient group has been created by working on DWI signs and leison volumes were calculated. For full article see PMID: 25634003 .
A new study by Hüseyin Boyacı has been published in Journal of Vision. In early retinotopic areas of the human visual system,information from the left and right visual hemifields 2 (VHFs) is processed contralaterally in two hemispheres. Despite this segregation, we have the perceptual experience of a unified, coherent, and uninterrupted single visual field. How exactly the visual system integrates information from the two VHFs and achieves this perceptual experience still remains largely unknown. In this study using fMRI, candidate areas that are involved in interhemispheric integration and the perceptual experience of a unified, global motion across VHFs has been explored.

Ilhan Atagun of Ataturk hospital working with a group of investigators including Oktay Algin of UMRAM investigated certain regions of the brain using magnetic resonance spectroscopy in patients with psychological disorders. In the study on 30 patients they found abnormalities in chemistry of their brain. The title of the associated manuscript is "Investigation of Heschl's gyrus and planum temporale in patients with schizophrenia and bipolar disorder: A proton magnetic resonance spectroscopy study". Authors are M.İ. Atagün, E.M. Şıkoğlu, S.S. Cana, G. Karakaş-Uğurlu, S. Ulusoy-Kaymak, A. Çayköylü, O. Algın, M.L. Phillips, C.M.Moore, D. Öngür. The article was published in Schizophr. Res. in 2014.
A new artice by Huseyin Boyaci has been published in Journal of Vision. In this study the effects of contiguity and figure-ground organization on the area rule of lightness is investigated.In a simple two-dimensional (2D) display composed of two uniform surfaces with different luminances, the lightness of the darker surface varies as a function of its relative area while its luminance is held constant (Gilchrist & Radonjić, 2009; Li & Gilchrist, 1999). This phenomenon is known as the area rule of lightness, and although it is extensively studied in the literature, the underlying principles are still largely unknown.

Asst. Prof. Katja Doerschner, a faculty member of UMRAM, Department of Psychology and Neuroscience Program at Bilkent University, has been recently awarded Sofja Kovalevskaja Award from Alexander von Humboldt Foundation. She is among the 11 scientists this year who has been awarded within the framework of this interdisciplinary grant. The objective of Sofja Kovalevskaja Award is to support young exceptionally promising researchers from abroad and enable them to establish their own junior research groups at research institutions in Germany. Dr. Doerchner will be at Justus Liebig University Giessen, Germany for 5 years. We would like to congratulate Dr. Doerschner for this prestigious prize and wish best for her academic life.
Assoc. Prof. Hüseyin Boyacı, a faculty member of UMRAM, Department of Psychology and Neuroscience Program at Bilkent University, has been recently awarded Senior Fulbright Scholar Award by Turkish Fulbright Education Commission to pursue his research, teaching and training abroad during the 2014-15 academic year. Dr. Boyacı will be at the University of California, San Diego (UCSD) during this academic year. As UMRAM family, we would like to congratulate Dr. Boyaci and wish best for rest of his academic life.
A new Article by Prof. Dr. Kader Karli Oguz and Arzu Ceylan Has has been published in Psychiatry Research: Neuroimaging. In this study 12 weeks of clozapine treatment on DTI ﬁndings in patients with schizophrenia has been investigated and the ﬁndings have been compared with those in unaffected controls. After 12 weeks of treatment with clozapine, white matter FA was increased in widespread brain regions. This suggests that this treatment alters white matter microstructural integrity in patients with schizophrenia previously treated with typical and/or atypical antipsychotics and, in some locations, reverses a previous deﬁcit.
