Computational neuroscience

Gianluca Susi Research line coordinated by Gianluca Susi.

Computational neuroscience is an interdisciplinary field which employs mathematical models and theoretical analysis to understand the principles that govern the physiology, structure and development of the nervous system, and related cognitive abilities.
Specifically, in the laboratory we carry out brain network simulations based on real data, aimed at:

1) understanding the mechanisms underlying the progression of neurodegenerative diseases through the study and reproduction of typical functional connectivity patterns and their disruption;

2) designing and testing personalized protocols of non-invasive electrical stimulation (e.g. tACS), focused on the modulation of oscillatory activity and synchronization between specific brain areas.
