Brief Summary

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

The management of many brain pathologies involves obtaining a functional and histological diagnosis and performing neurosurgery when possible. Histological diagnosis makes it possible to differentiate healthy areas from pathological areas. Functional diagnosis allows the identification of brain areas to be spared during neurosurgery in order to avoid any permanent post-operative disability.

The visual analysis of the color and texture of the brain by the trained eye of the neurosurgeon is largely part of his operating practice. It allows it to differentiate between healthy and pathological areas. Likewise, color variations linked to the functional activation of brain areas are sometimes visible to the naked eye. However, this approach is not optimal due to the limits of human vision. It is also very strongly dependent on the experience and expertise acquired by the neurosurgeon. This approach is therefore largely limited in many operating contexts: low visual contrasts, less experienced neurosurgeon.

Video Capture

Brain of patients, presenting a brain pathology eligible for a neurosurgery operation requiring a standard functional and/or histological diagnosis at HCL, will be video recorded with colorimetric cameras in order to evaluate the feasibility of identifying tissue.

Group Type EXPERIMENTAL

Videorecording

Intervention Type OTHER

Two cameras will be used to make the recordings: a classic camera placed on a stand 1 meter from your head, outside the sterile area and the color camera of the microscope used for the surgery.
