Vision: a systems neuroscience perspective
(Uskudar University, 2014)The visual system is the most studied part of the cortex, providing a basis for understanding not only visual processing per se but also the fundamental operations of the brain in general. Significant progress has been ... -
Visual crowding illustrates the inadequacy of local vs. global and feedforward vs. feedback distinctions in modeling visual perception

What crowding can tell us about object representations
(Association for Research in Vision and Ophthalmology Inc., 2016)In crowding, perception of a target usually deteriorates when flanking elements are presented next to the target. Surprisingly, adding further flankers can lead to a release from crowding. In previous work we showed that, ... -
What to choose next? a paradigm for testing human sequential decision making
(Frontiers Research Foundation, 2017)Many of the decisions we make in our everyday lives are sequential and entail sparse rewards. While sequential decision-making has been extensively investigated in theory (e.g., by reinforcement learning models) there is ... -
The whole warps the sum of its parts: gestalt-defined-group mean size biases memory for individual objects
(SAGE Publications Inc., 2017)The efficiency of averaging properties of sets without encoding redundant details is analogous to gestalt proposals that perception is parsimoniously organized as a function of recurrent order in the world. This similarity ... -
Why vision is not both hierarchical and feedforward
(Frontiers, 2014)In classical models of object recognition, first, basic features (e.g., edges and lines) are analyzed by independent filters that mimic the receptive field profiles of V1 neurons. In a feedforward fashion, the outputs of ... -
X‐Space MPI: magnetic nanoparticles for safe medical imaging
(Wiley, 2012)One quarter of all iodinated contrast X‐ray clinical imaging studies are now performed on Chronic Kidney Disease (CKD) patients. Unfortunately, the iodine contrast agent used in X‐ray is often toxic to CKD patients’ weak ... -
Zebrafish aging models and possible interventions
(InTechOpen Press, 2018)Across the world, the aging population is expanding due to an increasing average life expectancy. The percentage of elderly over the age of 65 is expected to be more than 15% of the total world population by 2025. As the ... -
Zebrafish-A model organism for studying the neurobiological mechanisms underlying cognitive brain aging and use of potential interventions
(Frontiers Media S.A., 2018)Classically, the zebrafish model organism has been used to elucidate the genetic and cellular mechanisms related to development since the embryo forms and grows externally following fertilization. This provides insight ...
