The Central Sulcus

The central sulcus — the landmark fissure dividing the frontal and parietal lobes — sits at the boundary between motor output and sensory processing. It is one of the most reliably identified structures in neuroimaging, and one of the most important to get right.

This site takes its name from that landmark. The tools here are built around the same idea: clear boundaries, reliable structure, and precision in the details that matter.

Each tool was developed from real clinical workflows — tumor board tracking, structured reporting, imaging protocol selection — and refined for the way radiologists actually work. Every tool runs entirely in the browser; no data is transmitted or stored.

Quick Reference

Key neuroanatomy landmarks

Sagittal brain anatomy most relevant to neuroimaging interpretation.

Central Sulcus neuroimaging illustration
Central Sulcus
The primary landmark dividing the precentral gyrus (primary motor cortex, Brodmann area 4) from the postcentral gyrus (primary somatosensory cortex, areas 3, 1, 2). Reliably identified on sagittal MRI by the hand knob ("omega sign") at the dorsal convexity.
Precentral Gyrus
Anterior to the central sulcus. Primary motor cortex. Loss of gray-white differentiation on DWI indicates acute cortical infarct; restricted diffusion without swelling distinguishes acute from chronic.
Corpus Callosum
The major white matter commissure connecting hemispheres. Key for detecting callosal dysgenesis, demyelination (MS), and "butterfly" glioblastoma crossing the midline via the splenium or body.
Sylvian Fissure
Lateral sulcus separating the temporal lobe from frontal and parietal lobes. Asymmetric enlargement raises concern for prior injury, atrophy, or mass effect displacing the fissure.
