Here is the abstract:
Bat echolocation is a dynamic behavior that allows for real-time adaptationsin the timing and spectro-temporal design of sonar signals in response to a particular task and environment. To enable detailed, quantitative analyses of adaptive sonar behavior, echolocation call design was investigated in big brown bats, trained to rest on a stationary platform and track a tethered mealworm that approached from a starting distance of about 170 cm in the presence of a stationary sonar distracter. The distracter was presented atdifferent angular offsets and distances from the bat. The results of this study show that the distance and the angular offset of the distracter influence sonar vocalization parameters of the big brown bat, Eptesicus fuscus. Specifically, the bat adjusted its call duration to the closer of two objects, distracter orinsect target, and the magnitude of the adjustment depended on the angular offset of the distracter. In contrast, the bat consistently adjusted its call rate to the distance of the insect, even when this target was positioned behind the distracter. The results hold implications for understanding spatial information processing and perception by echolocation.

On last Saturday, the 5th of June, I as a member of Group Anadolu, under the leadership of Husnu Aydogdu, performed in the Washington Folk Festival. Our group on that day consisted of Husnu Aydogdu, myself, Suphi Maruf, Sarah Olmstead (please take a look at her fundrasing page ), Alkan Donmez and Greg BenAvram. It was a great festival and we enjoyed playing to a large group of audience. |

I am joining APLAB directed by Dr. Michele Rucci as a postdoctoral researcher. The main focus of the laboratory is the role of the eye movements in visual perception, performance and development using psychophysical, computational and neuromorphic robotics methods. This focus well overlaps with my interest that is understanding the involvement of sensorimotor interactions in the development of perception and emergence/occurrence of percepts (a phenomenological approach to perception). More on my thoughts on this direction can be found: - My blog (soon to be started)

On May 3rd, 2009 Monika Megyesi and I are finally got married after 7 years of dating. The event took place at the home of Mary and Tilden Edwards. The ceremony performed by our dear friend Tilden H. Edwards , Jr, founder and senior fellow of Shalem Institute for Spirutual Formation, an Episcopal priest
and the author or editor of six books related to the spiritual life, in the presence of the family. Our 7-year journey together has been filled with joy and struggles of learning to live together and becoming more than we could ever be separately, thanks to our different background and experiences that helped enrich eachother's identity. The event was reflecting this fact: an Hungarian girl with Jewish decent, born in Romania and imigrated to Hungary, an expert in conflict management and a Muslim, Turkish boy, an engineer turned neuroscientist, married, on the other side of the world (USA), by an Episcopal priest whose love of God and people transcends beyond the construct of any individual religion and philosophy. |
