A method of monitoring a user's neuronal activity (10) includes recording a user's behavioural output with a portable electronic device, such as a mobile cellphone. The user's behavioural output (14) is compared (18) with predefined behavioural outputs associated with known event-related neuronal activations (20). The user's event-related neuronal activation (22) is determined based upon the comparison so as to provide an indication of the user's neuronal activity.
