社交大脑在青春期经历发育变化，推测青春期激素有助于这种发育。我们使用功能磁共振成像来探索青春期指标（睾酮、雌二醇和 DHEA 的唾液浓度；青春期阶段；初潮状态）如何与社交情绪任务期间的大脑活动相关。 42 名年龄在 11.1 岁至 13.7 岁之间的女性接受了功能磁共振成像扫描，同时阅读与社会情绪相关的场景（需要表征另一个人的心理状态）或与基本情绪相关的场景（不需要表征）。青春期阶段和初潮状态用于将女孩分配到青春期早期或晚期组。在整个样本中，社交情绪与基本情绪之间的对比导致了社交大脑网络内的活动，包括两个半球的背内侧前额叶皮层（DMPFC）、后颞上沟和前颞叶皮层（ATC）。激素水平升高（与年龄无关）与社交情绪处理过程中左 ATC 活动升高相关。年龄较大（与激素水平无关）与社会情绪处理过程中 DMPFC 活性较低相关。我们的研究结果表明，青春期激素和年龄对青少年社交大脑具有功能上分离的影响。
The social brain undergoes developmental change during adolescence, and pubertal hormones are hypothesized to contribute to this development. We used fMRI to explore how pubertal indicators (salivary concentrations of testosterone, oestradiol and DHEA; pubertal stage; menarcheal status) relate to brain activity during a social emotion task. Forty-two females aged 11.1 to 13.7 years underwent fMRI scanning while reading scenarios pertaining either to social emotions, which require the representation of another person’s mental states, or to basic emotions, which do not. Pubertal stage and menarcheal status were used to assign girls to early or late puberty groups. Across the entire sample, the contrast between social versus basic emotion resulted in activity within the social brain network, including dorsomedial prefrontal cortex (DMPFC), the posterior superior temporal sulcus, and the anterior temporal cortex (ATC) in both hemispheres. Increased hormone levels (independent of age) were associated with higher left ATC activity during social emotion processing. More advanced age (independent of hormone levels) was associated with lower DMPFC activity during social emotion processing. Our results suggest functionally dissociable effects of pubertal hormones and age on the adolescent social brain.
