Part 1: project profile
Project name
Aperiodic visual stimulation in a VEP-based BCI
Project short description
Visual-evoked potentials (VEPs) are a possible way to drive the a Brain-Computer Interface (BCI). This projects aims at maximizing the discrimination between different stimuli by using numerical codes derived from techniques of digital telecommunications.

Laboratory work and risk analysis
(work in progress) Several EEG sessions will be recorded. Data acquisition is performed at the IIT-Lab. All risks are those related to the use of video terminals and EEG devices.
Part 2: project description
What this project means to demonstrate is the possibility to extend the SSVEP paradigm to multiple visual signals (i.e. blinking lights) using a numeric encoding, in a way similar to what has already been attempted with noise-tagging.
