ClinConnect Summary

This clinical trial is studying how our brain perceives the time it takes for moving objects to reach us, which is an important skill we use in everyday life, like catching a ball or avoiding a moving vehicle. During brain surgery to remove a tumor, patients are temporarily woken up so that doctors can precisely locate the tumor and avoid damaging healthy brain tissue. While the patient is awake, researchers will conduct tests to understand which areas of the brain are involved in this perception.

To participate in this study, patients must have a brain tumor that does not affect their dominant hand and should be able to see well. They must also agree to the study terms and not have any eye movement disorders. The trial is open to all genders and includes a control group of healthy individuals who meet similar vision and health criteria. Participants can expect to be involved in the study during their surgery, where their brain activity will be monitored while they perform specific tasks. It's important to know that certain conditions, like tumors located in specific brain areas or serious neurological diseases, may exclude someone from participating.

• • Who will agree with all terms and sign the experimental agreement
• • Correct or corrected vision
• • With no known oculomotor abnormalities.
• • Affiliated to a social security system
• Exclusion Criteria:
• For the patients:
• • Brain tumor located in the occipital area
• • Legally protected patient, or with unknown ability to sign the experimental agreement, as determined by the medical team.
