OVERVIEW

The aim of the course is to introduce the state-of.the art in the field of neural-interfaces. Hardware interfaces (neuro-electronic systems); techniques for measuring the electrophysiological activity of excitable cells and tissues; analysis techniques for neuronal signal analysis (from micro-to-macro; from patch-clamp to EEG). Introduction to functional connectivity (connectome) and interplay between connectivity and dynamics (dynome). Introduction to code of information in neuronal systems and brain-machine-interface (BMI).
