Cortical Mapping evaluates brain function through evoked electrical response application or by recording physiological responses immediately pursuant to direct brain stimulation. This modality delineates brain anatomy despite normal variations present in each patient, enabling surgeons to precisely locate the area of concern while avoiding nearby brain structures.

Bromedicon employs several different methods during functional mapping. It is often based on SSEP data gathered through a contact grid applied to the brain surface. These contacts gather SSEP potentials that delineate the central sulcus, or fissure of Rolando, that divides sensory and motor strips. This very useful modality, appropriate for surgeons with extensive mapping experience, carries a small risk of seizure or bleeding.

Bromedicon personnel possess the very high skill level that is essential for monitoring data collection and mapping.
