Final answer:
The deactivation occurs in the prefrontal cortex, which is associated with executive functions, attention, and inhibiting distractions.
Step-by-step explanation:
The study by neuroscientist Gert Holstege and his colleagues shows that the prefrontal cortex of women's brains are deactivated while they experience orgasm. This area of the brain is known for its role in executive functions and goal-directed behaviors, such as working memory and attention. The deactivation of the prefrontal cortex during orgasm is significant as this part of the frontal lobe has also been implicated in playing a role in attention and inhibiting distracting thoughts and actions to focus on a goal.
