In this study, we investigated the use of single-point Raman spectroscopy (RS) to differentiate between normal brain tissue and focal cortical dysplasia (FCD) during epilepsy surgery. Initial RS measurements showed high background noise, but using a different Raman probe with fewer optic fibers, we were able to detect characteristic brain spectra bands in three patients. These bands confirmed the optical signature of normal brain tissue. While statistical significance was not achieved due to the limited number of patients, our study improved the technical methodology for processing brain signals and holds promise for intraoperative detection of FCD in epilepsy surgeries. Further research is needed to validate these findings and enhance surgical outcomes.
