Finding 1mm in the Brain | Functional Neurosurgery Explained – Episode 1

Brain surgeons must hit deep targets only a few millimeters wide, buried more than 10 cm inside the brain, with less than 1 mm error.

1 mm of error can change a patient's outcome in DBS and other functional procedures.

Functional neurosurgeons turn anatomy into a 3D coordinate system (X, Y, Z).

Skull landmarks and surface anatomy failed for deep targets.

Internal brain landmarks like the AC-PC line are important for targeting.

Stereotactic atlases and MRI work together in modern targeting.
