Cognitive neuroscience is a multidisciplinary academic field dedicated to the scientific study of the brain mechanisms that underlie cognitive processes, in both health and disease. Thus, we investigate a range of research questions, including memory, attention, affective processing, object recognition, sleep and dreaming, fear conditioning, gambling, ageing, neurodegeneration, and brain trauma. Techniques employed to tackle these questions comprise neuroimaging (MRI, fMRI, and MRS), electrophysiology (EEG and ERPs), and brain stimulation (tDCS).
