Summary: A recent study examines how brains anatomy affects cultural dominance in primates. Researchers discovered that squirrel monkeys ‘ uncinate fasciculus, a system responsible for memory and feeling, had a strong correlation with their dominance patterns.
This connection, which is in line with human research on social aggression, was particularly strong in the proper hemisphere. The findings point to an evolutionarily intact mind road that underlies species dominance.
Important Information
- Dominance Correlates: Higher social rank is related to appropriate uncinate fasciculus strength.
- Aggression, order, and obedience were the measures used in behavioral traits.
- Findings from cross-species studies on supremacy and anger are consistent with those from animal studies.

Julie Royo, from the Institute of Cerveau, and associates examined the physiology that supports cultural dominance in a recent study in the Journal of Neuroscience .  ,
In 15 rabbit monkeys, the researchers examined fundamental brain characteristics and behavioral indicators of cultural dominance and examined brain regions associated with human emotion, motivation, and memory.
These behavioral indicators included obedience, anger, and hierarchy.
Royo and colleagues discovered that the uncinate fasciculus, one of the brain regions they concentrated on, was significantly associated with their cultural dominance methods.
This was especially real for the right hemisphere’s uncinate fasciculus.  ,
These findings support animal studies that link social aggression to this brain region, suggesting that social dominance may be a species-specific evolutionary substrate.  ,

Abstract
Information for a Social Dominance with Evolutionary Continuity: Perspectives from Nonhuman Primates Tractography
In non-human apes, the dynamics of social supremacy have a significant impact on access to resources and the success and survival of reproduction.
These relationships are based on antagonistic and compulsive relationships that result in specific, hierarchical social structures.
The use of mental scanning based on tractography has identified essential neuronal network of the limbic system main social behavior in humans, whose social behavior is equally organized.
The uncinate fasciculus and the cingulum package, two of which, have been linked to anger and some neuroticism, are two of them.
In this study, we used advanced tractography to examine the social dynamics of connections in a group of 15 female squirrel monkeys ( Saimiri sciureus ) from the same species.
We compared the biostructural characteristics of the uncinate fasciculus and cingulum with psychological order indicators while taking into account variables like age, weight, asymmetry, head size, and physiological effects. The cortex, a limbic relationship involved in storage, was also included as the control tract.
Our findings link the integrity of the proper uncinate fasciculus with cultural dominance indicators like normalized David’s scores, aggressive behavior, and submissive behavior.
The left uncinate fasciculus’ trends point to potential diplomatic engagement with a correct hemispheric lateralization.
These findings support the hypothesis that cultural hostility and disorders are related to the uncinate fasciculus, which would imply that there has been an evolutionary resemblance between the neuro-anatomical materials of cultural dominance dating at least to at least 35 million years.
