Attentional modulation of hierarchical speech representations in a multitalker environment
(Oxford University Press, 2021-11)Humans are remarkably adept in listening to a desired speaker in a crowded environment, while filtering out nontarget speakers in the background. Attention is key to solving this difficult cocktail-party task, yet a detailed ... -
Biased competition in semantic representations across the human brain during category-based visual search
(Bilkent University, 2017-01)Humans can perceive thousands of distinct object and action categories in the visual scene and successfully divide their attention among multiple target categories. It has been shown that object and action categories are ... -
Contrast affects fMRI activity in middle temporal cortex related to center-surround interaction in motion perception
(Frontiers Research Foundation, 2016)As the size of a high contrast drifting Gabor patch increases, perceiving its direction of motion becomes harder. However, the same behavioral effect is not observed for a low contrast Gabor patch. Neuronal mechanisms ... -
Distinct representations in occipito-temporal, parietal, and premotor cortex during action perception revealed by fMRI and computational modeling
(Elsevier, 2019)Visual processing of actions is supported by a network consisting of occipito-temporal, parietal, and premotor regions in the human brain, known as the Action Observation Network (AON). In the present study, we investigate ...
