Answer: Cerebellum
Explanation: Cerebellum, or "little brain" in Latin, is located in the hindbrain, and thanks to this hindbrain, motor functions and skills are regulated, making Jennette world-class in gymnastics. These motor skills include coordination, balance and posture. In addition, the cerebellum plays an important role in cognitive functions such as language, attention, emotional functions and regulating, for example, fear, and processing of memory. Because of that ability to process memories, Jennette remembers exactly how long it took her to reach this level of performance.
