Gender Differences in Amygdala
Medical experts have the ability to distinguish between the amygdalae of males and females. It has been observed that by the age of 11, the male amygdala tends to be larger than its female counterpart. Moreover, research suggests that memory functions are more dominant in the left amygdala of females, while in males, it is more prominent in the right amygdala. A study conducted on this topic discovered that female amygdalae enable women to retain stronger memories of emotional events compared to males. Additionally, the right amygdala is responsible for initiating actions, which may explain why males often respond physically to emotional situations.
Roles of Hemispheres in the Amygdala
The amygdala, located in both hemispheres of the brain, serves different functions depending on its placement. While the left amygdala is involved in inducing both positive and negative emotions such as happiness, fear, anxiety, and sadness, the right amygdala primarily triggers negative emotions, particularly fear and sadness. This distinction explains the left hemisphere amygdala’s potential role in the brain’s reward system, while the right hemisphere amygdala is closely tied to fear conditioning and the fear response.
