Background and Aim: In the present study, the cerebral surface landmarks in human fresh autopsy specimens were investigated.


Methods and Materials/Patients: Totally, 37 fresh adult autopsy human brain specimens from the Rasht Forensic Medicine Center were
enrolled. Four specimens were excluded because of some traumatic injuries to cerebral cortex. Demographic information of all cases was
obtained. Length of bilateral central sulcuses and posterior ramous of Sylvian fissures, thickness of superior, middle, and inferior gyri of
temporal lobes, as well as the distance from frontal poles to midpoint of central sulcuses were measured and analyzed using SPSS software.


Results: In total, 25 male (75.8%) and 8 female (24.2%) specimens were included. Mean (range) length of posterior ramus of right and left
Sylvian fissure was 75.61 mm (50-95) and 74.55 mm (49-100), respectively. Mean (range) length of right and left central sulcus was 94.85
mm (75-115) and 97.24 mm (65-125), respectively. Mean (range) thickness of right and left superior temporal gyrus was 16.66 mm (5-20)
and 15.33 mm (7-25), respectively. Mean (range) thickness of right and left middle temporal gyrus was16.63 mm (5-25) and 16.42 mm (8-
25), respectively. Mean (range) thickness of right and left inferior temporal gyrus was 10.30 mm (5-20) and 10.70 mm (5-22), respectively.
Mean (range) distance from right and left frontal pole to midpoint of right and left central sulcuse was 81.27 mm (55-105) and 82.63 mm
(60-105), respectively. There were no statistically significant differences between two h emisphere measurements.


Conclusion: It can be said that the two hemispheres are similar in cerebral surface landmarks.
