Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this study is the multimodal exploration via eyetracking, MRI and EEG data of ocular movements and the corresponding brain activation during ecologic visual stimulation in the healthy population.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Cerebral activation following visual stimulation is explored using two neuroimaging techniques EEG and MRI while eye movements are recorded. Three experiments are performed: in MR scanner 1) functional localisation of specific areas: LOC, FFA, MT/V5, V1 and V2 and 2) a saccadic choice experiment; with EEG, replication of the experiments performed in the MR scanner and 3) an additional experiment of movement detection during the ocular saccades.

Thirty young volunteers (18-40 y old) are involved.
