Dorsal hippocampal commissure

The dorsal hippocampal commissure (DHC) is a white matter tract that provides interhemispheric connections between temporal lobe brain regions.

In that short-term trial, which was conducted during invasive monitoring in the epilepsy monitoring unit, LFS (5 Hz) of the human dorsal hippocampal commissure reduced temporal lobe seizures by 90%. As this fiber tract is very close to the posterior arching fornices, the target was termed the fornico-dorso-commissural tract.
