Abstract
An issue that is often debated in forensic traumatology is the differential diagnosis of hemorrhages into the human brain substance (HBS) of traumatic and non-traumatic genesis.
 Objectives. This study aims to identify new criteria for objective forensic differentiation of hemorrhages of traumatic origin, cerebral infarction of ischemic and hemorrhagic genesis by using the method of complex degree of mutual anisotropy. For this study native sections of HBS from 125 corpses were used in the case of: death from coronary heart disease - 35 (28%) of native sections (Group 1 - control); hemorrhages of traumatic genesis - 30 (24%) sections (Group 2); ischemic cerebral infarction - 30 (24%) native sections(Group 3); and hemorrhages of non-traumatic genesis - 30 (24%) native sections (Group 4).
 Results. The statistical moments of the third and fourth orders, which characterize the asymmetry and excess of the complex degree of mutual anisotropy module size distributions, the strength of the method of polarization-correlation microscopy in the differentiation of the samples of the histological sections of the brain of control and experimental groups reached a good level — 87%-90%.
 Conclusion. The method of complex degree of mutual anisotropy allows differentiating with great precision the genesis of hemorrhage into the substance of the brain.
Highlights
Among the injuries, mechanical injuries occupy one of the leading places, and traumatic brain injuries are among them the most common (Konovalov, 2001)

Differential diagnosis of the cause of death (CD) from ischemic brain infarction (IBI), hemorrhages of traumatic (HTG), and non-traumatic (HNG) genesis helps to eliminate the suspicion of a violent cause of death (Pigolkina, et al, 2012; Leontiev, 2016)
Summary
Mechanical injuries occupy one of the leading places, and traumatic brain injuries are among them the most common (Konovalov, 2001). One of the debating issues in forensic traumatology is the differential diagnosis of hemorrhages into the human brain substance (HBS) of traumatic and non-traumatic genesis. Differential diagnosis of the cause of death (CD) from ischemic brain infarction (IBI), hemorrhages of traumatic (HTG), and non-traumatic (HNG) genesis helps to eliminate the suspicion of a violent cause of death (Pigolkina, et al, 2012; Leontiev, 2016). The preparation of reagents, and subsequently histological preparations of HBS by appropriate staining methods, require from one-to-several days, which does not always satisfy the requirements of the judicial authorities (Khokhlov, 2010). More and more attention is being paid to optical methods for the study of biological tissues using lasers which, by studying the lightscattering phenomena, make it possible to obtain reliable objective data on the dynamics of pre- and post-mortem changes of the studied tissues of the human body and with greater accuracy to diagnose CD because of hemorrhage into the substance of the brain (Bachinskiy, 2017)
