Perception is affected by immediate pattern of sensory inputs and prior experiences acquired through associations. Relatively very little attention has been given to the means by which experiences interact with incoming sensory signals. In a recent study published in Frontiers in Integrative Neuroscience, Can Oluk and Dr. Hulusi Kafaligonul aimed to understand how prior experiences acquired through multisensory associations shape the subsequent motion perception. By using motion types tapping low-level motion mechanisms, they found that audiovisual associations influence low-level motion perception and these associations play a role at early stages of motion processing.

The groundbreaking ceremony for the new building of Aysel Sabuncu Brain Research Center which will also home UMRAM took place on April 30,with the attendance of the Minister of Science, İndustry and Technology. The center has been established through a donation agreement between philanthropist Aysel Sabuncu and Bilkent University.

 Aysel Sabuncu Brain Research Center will also be supported by UMRAM and open to researchers from all universities as the contuniation of  UMRAM tradition. Beside brain research one of the most important purpose of the center is to encourage and promote multidisciplinary research practices which is considered to be the most effective method to pave the way of developing  novel technologies in all fields of science worldwide. Therefore scientists from Turkey and abroad in the fields of medicine, physics, molecular biology and genetics, psychology and engineering will be welcome to use the facilities in the center and also have the opportunity of collaborating with the researchers of other fields. The Sabuncu Brain Research Center will be the first such facility in Turkey.

 Construction which is in Bilkent Cyberpark is scheduled to be completed within a year.

The 5th International Workshop on Magnetic Particle Imaging (IWMPI 2015) has been held in Istanbul, Turkey between 26-28 March 2015. 150 researchers from 14 countries attended the 3-day workshop. The workshop featured 43 oral presentations, 64 poster presentations, 4 keynote speeches, and 6 tutorial talks. The proceedings of the workshop will be published online on IEEEXplore Conference Publications. The workshop was organized largely by UMRAM in collaboration with Bilkon, and UMRAM faculty member Asst. Prof. Emine Ulku Saritas chaired the workshop.

Asst. Prof. Tolga Cukur, a faculty member of UMRAM, Department of Electrical and Electronics Engineering and Neuroscience Program at Bilkent University, has been recently awarded the EMBO (European Molecular Biology Organization) Installation Grant. He is among 8 scientists this year who have been selected for this grant. The objective of the Installation Grant is to support young scientists in life sciences to establish their own research groups in member states. See more information here.

A recent study by Dr. Tolga Cukur of UMRAM has been published in IEEE Transactions on Medical Imaging. The study describes a novel image acquisition/reconstruction strategy that mitigates signal loss in rapid steady-state free precession (SSFP) imaging. Although SSFP imaging offers very high SNR efficiency, it suffers from signal loss in regions of large magnetic field inhomogeneities. The developed strategy combines tailored data acquisition patterns with compressed sensing reconstructions to minimize signal loss without increasing scan time. Click here for the full article.

A new study by Dr. Tolga Cukur of UMRAM has been published in Magnetic Resonance in Medicine. The study develops a new technique that enables reliable fat/water separation for ultra-fast MRI acquisitions. The proposed technique is a significant advancement over state-of-the-art methods, and it enables a significantly more favorable trade-off between background suppression and broadband excitation during rapid imaging. In vivo experiments conducted during the study show robust performance in the presence of field inhomogeneities, promising great clinical utility. Click here for the full article.

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 .
