Brain structure linked to social dominance identified in squirrel monkeys

Brain structure linked to social dominance identified in squirrel monkeys

In a new JNeurosci paper, Julie Royo, from the Institute of Cerveau, and colleagues explored the neuroanatomy that underlies social dominance in nonhuman primates.

Right-Sided Brain Pathway Linked to Social Dominance

A new study uncovers how brain anatomy relates to social dominance in primates. Researchers found that the uncinate fasciculus, a tract tied to emotion and memory, strongly correlated with dominance behaviors in squirrel monkeys. This link was especially pronounced in the right hemisphere, aligning with human findings on social aggression.
