Taylor Haughton line

In 1900 Taylor and Haughton described a technique to define a line on the scalp directly above the central fissure 1)

1. Draw a Nasion-Inion line ( Nasion – Just below Glabella and Inion -External Occipital protruberance)

2. Divide the Nasion-Inion line in to 25%, 50% and 75%

3. Bregma is the point between the 25% and 50% points and Lambda is at 75% point

4. Sylvian fissure is drawn from the orbitotemporal angle (A point of depressin where eyebrow ends) to the 75% point on naso-inion line.

5. Draw a line perpendicular to the root of the zygoma starting at preauricular point

6. Central sulcus is drawn from 54% point on naso-inion line to the point where the sylvian line cuts the perpendicular line
