And there were still more radical procedures, prefrontal lobotomy for instance.
The brain (Fig. 70) is seen to be very narrow and low in the prefrontal area, the seat of the higher mental faculties.
The exact position of the suture between the prefrontal and postfrontal is not known.
The prefrontal articulates with the anterolateral process of the frontal.
The anterior part of this margin, however, may be formed by a prefrontal, which is not clearly set off by a suture.
The posterior surface of the prefrontal forms the anterior wall of the orbit of the eye.
In each case when a preocular is lacking, the "preocular" and prefrontal are fused.
The vomers terminate midway between the median nares and the descending process of the prefrontal.
The relative lengths of the prefrontal and internasal sutures are subequal, or the prefrontal suture is slightly longer.
The hinder end of the vomer articulates with the end of the descending process of the prefrontal.
prefrontal pre·fron·tal (prē-frŭn'tl)
Of, relating to, or situated in the anterior part of the frontal lobe.
Situated anterior to the frontal bone.
