All you anatomy and physiology brainiacs out there! (no pun intended.) Anyone know how to easily find the central sulcus on the human brain and possibly the sheep's brain? I know where it is on the diagrams but its a b*itch trying to find it on the real thing. HELP?!

It is actually the complete opposite side of the brain-stem (spinal cord)
If you will be holding the sheep brain, the main sulci are more easily separated than the others (after removal of the dura and arach matter).
While other sulci intersect with the longitudinal fissure at angles, the central sulcus hits it almost perpindicular.

"The central sulcus is a fold in the cerebral cortex of brains in vertebrates. Also called the central fissure, it was originally called the fissure of Rolando or the Rolandic fissure.
The central sulcus is a prominent landmark of the brain, separating the parietal lobe from the frontal lobe and the primary motor cortex from the primary somatosensory cortex."
I would imagine from reading this that it would be located somewhere near where the spinal cord would've been...good luck. Wish I could help more but I have no fresh brains to look at right now :)

If you hold the brain with the brain stem closest to you, the central sulcus will be just posterior to the actual midline of the brain separating it into anterior and posterior sections.
