ANATOMO-MORPHOMETRIC STUDY OF THE ANTERIOR CEREBRAL COMMISSURE IN NON-NEUROLOGICAL ADULT BRAINS.

The commissural pathways of the brain have represented a point of interest for anatomists beginning with the 19th century. However, only by mid 1950s Theodor W. Blackstad achieved the experimental analysis of their functional organisation. The canal of the anterior commissure and its lateral segment were mentioned beginning with the 18th century by Vicq D'Azyr, so that in 1983 Malcolm D. Carpenter would achieve the first anatomical description of the rostral commissure. The purpose of this study is to achieve a morphometrical analysis of the mediosagittal segment of the anterior cerebral commissure, constituting an important landmark in surgical interventions at the level of the anterior wall of the third cerebral ventricle. The anatomical material is represented by 20 adult brains in the collection of "Ion Iancu" Anatomy Institute of "Gr. T. Popa" University of Medicine and Pharmacy Iaşi. The anatomical pieces were preserved through immersion into a formaldehyde solution 10% for 6 months. The images were taken with the help of a Fujifilm FinePix S3200 camera, with a resolution of 10 megapixels and processed with the ArchiCAD software. Through the measurements taken regarding the maximum and the minimum diameter, as well as through the determination of the area of the mediosagittal section, our study represents a first basis in the carrying out of an anatomical norm regarding the anterior white commissure.
