Research in CCBS is highly interdisciplinary across all faculties at UM. Thus, CCBS is uniquely positioned to create the bridge that foster engagement, increase diversity, and promote interdisciplinary learning and collaboration in the cognition and brain sciences at UM. The research in CCBS currently focused along with the four areas:

Macao is a multicultural and world’s entertainment capital, which offers excellent brain research resources for the study of addiction and decision making. The platform in CCBS can help reveal neural mechanism of addiction, and explore new methods of intervention and treating addictive behaviors.

Fig. Participants in the guilty group exhibited significantly higher HbO concentration changes in response to the probe stimulus compared to that from irrelevant stimuli in (Left: fNIRS brain activation maps). For the guilty group, the probe stimulus elicited significantly larger amplitude of P300 than the irrelevant ones (Right: ERP components and EEG brain topography)
Macao is a multicultural and multilingual area, which offers excellent brain research resources in language, translations and cognitive linguistics involved the Cantonese, Mandarin, Portuguese and English. The platform in CCBS can reveal the brain cognition mechanism associated with multilingualism and multilingual translation.

Macao’s average life expectancy is ranked No. 2 in the world, which can result in issues related to cognitive aging and increased incidence of brain disorders. In addition, children’s brain development is essential for the future of Macao. The CCBS’s brain plan should also focus on the study of children’s brain cognitive mechanism and behavior, promoting children’s brain development and personality shaping. Further, early prevention, early diagnosis, early treatment and intervention, and therapeutic evaluation methods development for brain disorders is one of the core topics of CCBS’s brain projects.

Neuroimaging techniques have changed the way neuroscientists address questions about functional anatomy, especially in relation to behavior and clinical disorders. Neuroimaging includes the use of various techniques to either directly or indirectly image the structure or function of the brain. The core facility in CCBS is the functional magnetic resonance imaging (fMRI) system. fMRI uses magnetic resonance imaging to measure the changes in hemodynamics including blood oxygen and blood flow induced by neuronal activity, which can be used to map the brain activation and brain networks in frequency-temporal-spatial domain in order to systematically study the neural mechanisms associated with brain cognition and brain disorders. In addition to 3T fMRI, the comprehensive research platform in CCBS also include other functional neuroimaging platforms such as electroencephalograph (EEG), functional near-infrared spectroscopy (fNIRS) or other fused multimodal neuroimaging techniques.
