Addressing some of the fundamental questions in cognitive neuroscience requires a deep knowledge about the organization of cerebral cortex. As cortical cartographers, we aim to comprehensively investigate the structure, function, and connectivity of human cerebral cortex using MRI, fMRI, DTI, and other neuroimaging methods. In our projects, we extensively use publicly available databases such as Human Connectome Project database. Data are also collected in the neuroimaging centers of IPM and NBML. We employ various computational and machine learning techniques to analyze large-scale neuroimaging datasets.

Achievements and Future works
During the last decade, we were studying the neural basis of different cognitive functions esp. attention and perception [1,2]. We tried to study how the brain changes the neural oscillations to orient attention to a specific aspect of an object. Using a wide range of brain signals from various species of the rodent, non-human primate and human subjects, and also based on edge-cutting engineering methods, we have approached this purpose. Our results show that attention has a close relation to neural oscillations (3). Recently, we developed our results based on a novel view of neural activity by considering both spike and LFP information together, so-called spike-phase coupling (SPC). We have also revealed the relation between this SPC and sensory information, behavior, and cognitive functions like attention and adaptation and working memory [4-6). In addition, to study the neural basis of cognitive functions, we also tried to improve the related methods to reach this aim [7-9). For future, we plan to extend our findings based on different neural data and develop some models based on these findings.
