I received my Bsc degree in Physics at the University of Porto, in 1996, and was accepted in the Gulbenkian PhD programme in Biology and Medicine (PGDBM). My PhD thesis was performed at the University of Sussex, Brighton, UK, on the neural mechanisms of learning and memory. In 2007, I joined Prof. Miguel Castelo-Branco’s laboratory at the IBILI (Faculty of Medicine, University of Coimbra) where I have been working as a Research Fellow in the field of human neuroscience.
I am interested in elucidating the brain mechanisms underlying cognitive control in the human brain and how these are disrupted in disorders affecting brain function. In particular, I am interested in understanding (1) how cognitive control is affected by ageing; (2) the role of neuromodulation in cognitive control; (3) how neuromodulation affects global brain dynamics and behaviour on a moment-to-moment basis; (4) the brain mechanisms underlying moment-to-moment fluctuations in performance associated with poor attentional control.
Recent advances in
signal processing have made it possible to non-invasively study the temporal
evolution of whole brain activity patterns at the single trial level. This is
an exciting time that promises to unravel not just where brain activity occurs,
but also how neural activity is coordinated from one moment to the next, from
brain region to brain region.
