An EEG Study on the Rhythmic Nature of Perception and Attention

Recruiting

• Conditions: Human Brain and Cognition

• Registration Number: NCT06236399
• Lead Sponsor: Università Vita-Salute San Raffaele

Brief Summary

The study involved healthy volunteers (n= 200), in a single center, low-risk intervention protocol of a non-profit nature. The objective of the study is to investigate the neural mechanisms of visual perception and attention, with particular reference to neural oscillations, in the general population through electroencephalogram (EEG) recording and the administration of simple visual tasks on a PC. The study presented is not associated with risks, as EEG is a non-invasive technique for which there are no known contraindications or adverse reactions.

Primary Outcome Measures

Name	Time	Method
Autism Quotient (AQ)	during the intervention	Personality questionnaire measuring subclinical autistic traits. Higher score mean worse outcome. Score range: min.= 0, max.= 50.
Electroencephalographic (EEG) oscillatory phase coherence	during the intervention	Phase coherence of EEG oscillations in theta, alpha and beta frequency bands
Schizotypal Personality Questionnaire (SPQ)	during the intervention	Personality questionnaire measuring subclinical schizotypal traits. Higher score mean worse outcome. Score range: min.= 0, max.= 74.
Electroencephalographic (EEG) oscillatory amplitude	during the intervention	Amplitude of EEG oscillations in theta, alpha and beta frequency bands
Electroencephalographic (EEG) oscillatory frequency	during the intervention	Frequency of EEG oscillations in theta, alpha and beta frequency bands
