ABSTRACT:

Introduction: The sulci of the human brain are specifically the result of an evolutionary infolding process. These are the anatomical structures which border and divide the adjacent gyri. Knowledge of pattern of sulci and their sulcul and intersulcal length is important for diagnosis of neurological, functional and cognitive disorders.

Aim: The aim of the study is to present the significance of morphological and morphometric measurements of sulci  of superolateral surface of frontal lobe and their comparison between right and left cerebral hemispheres.

Materials and methods:  The study comprised of 50 formalin fixed cerebral hemispheres 25 right and 25 left, of human cadaver of unknown sex which were obtained from the Department of Anatomy, Government Medical College, Amritsar. . All the parameters were taken by using standard digital vernier calliper and calibrated scale.

Result and conclusion:  All the sulci of superolateral surface of frontal lobe were found to be present in all the specimens of right and left cerebral hemispheres except AHR which was absent in 4%(2) specimens of the  right side. The mean length of CS and PreCS was found to be more in right hemispheres where as mean depth of both sulci was  more in left hemispheres. Mean length and depth of  lateral sulcus  was more in left side as compared to right. Mean length of SFS and IFS was greater in right hemispheres whereas the mean depth of both the sulci was found to be similar in both sides.  Hence the differences in sulcul length and depth indicate that the two cerebral hemispheres differ structurally and it can be speculated that some morphological asymmetries could be related to other functional hemispheric specialization.

KEY WORDS: Cerebral cortex, Pattern of sulci, Intersulcal length, Functional hemispheric specialization.
