在一個研究中，研究者在青少年們進行線索處理任務時用fMRI儀器掃描觀測腦部變化。第一個實驗時，青少年在完成任務後將獲得獎勵，另一個實驗則沒有獎勵。fMRI主要觀測的即為腦部獎勵機制進行時，腦部活動變化。接著，研究者收集了受試者的唾液用於睪固酮測定。研究結果顯示，上升的睪固酮濃度和青少年的行為無明顯關聯，但在第一個實驗（有獎勵）以及第二個實驗（無獎勵）時，腦部進行和獎勵機制相關的活動和上升的睪固酮濃度相關。在青少年執行有獎勵的任務時，上升的睪固酮濃度會引起更活躍的腦部活動。

In one study, researchers used fMRI scans to observe changes in the brains of teenagers while they performed a cue-processing task. In the first experiment, adolescents received a reward for completing the task, and in the other experiment, there was no reward. What fMRI mainly observes is the changes in brain activity when the brain's reward mechanism is in progress. Next, the researchers collected the subjects' saliva for testosterone measurements. The results of the study showed that there was no obvious correlation between rising testosterone concentrations and adolescent behavior. However, in the first experiment (with reward) and the second experiment (without reward), the brain performed activities related to the reward mechanism and increased testosterone. Concentration related. Elevated testosterone levels cause more active brain activity when adolescents perform rewarding tasks.

In one study, researchers used fMRI instruments to scan and observe brain changes during clue processing tasks in adolescents. In the first experiment, teenagers will receive rewards after completing tasks, while in the other experiment, there will be no rewards. The main observation of fMRI is the changes in brain activity during the reward mechanism of the brain. Next, the researchers collected the saliva of the subjects for testosterone measurement. The research results showed that there was no significant correlation between increased testosterone concentration and adolescent behavior, but in the first experiment (with reward) and the second experiment (without reward), brain activity related to reward mechanisms was correlated with increased testosterone concentration. Elevated testosterone levels can trigger more active brain activity when adolescents perform rewarding tasks.

In one study, researchers used fMRI instruments to scan and observe brain changes while teenagers were doing clue processing tasks. In the first experiment, teenagers will be rewarded after completing the task, while in the other experiment, there is no reward. FMRI mainly observes the changes of brain activity when the brain reward mechanism is going on. Then, the researchers collected the saliva of the subjects for the determination of testosterone. The results show that there is no obvious correlation between the rising testosterone concentration and adolescent behavior, but in the first experiment (with reward) and the second experiment (without reward), the brain activities related to reward mechanism are related to the rising testosterone concentration. When teenagers perform rewarding tasks, the rising testosterone concentration will lead to more active brain activity.
