A defibrillator works by delivering an electric shock to the heart to restore its normal rhythm. When the heart is in a life-threatening rhythm such as ventricular fibrillation or ventricular tachycardia, the defibrillator sends an electrical current through the heart muscle to depolarize the cells and allow the heart to reestablish an organized rhythm. This shock can help stop the abnormal rhythm and allow the heart to resume pumping blood effectively. Defibrillators are crucial in treating sudden cardiac arrest and can save lives by quickly restoring a normal heart rhythm. **

Memory is not intelligence in itself, but it is an important component of intelligence. Memory allows us to store and retrieve information, which is essential for learning, problem-solving, and decision-making. However, intelligence encompasses a broader range of cognitive abilities, including reasoning, problem-solving, and creativity, in addition to memory. While memory is an important aspect of intelligence, it is not the sole determinant of intelligence. **

Intelligence and photographic memory are two different cognitive abilities. Intelligence refers to the overall capacity for learning, reasoning, problem-solving, and adapting to new situations. Photographic memory, on the other hand, is the ability to recall images, sounds, or objects in great detail after only a brief exposure. While both can be beneficial in different ways, intelligence is generally considered to be a more valuable and versatile trait as it involves a broader range of cognitive skills beyond just memory. **

Nagato chose to revive the villagers and Kakashi's father with the Jutsu of Rinnegan Reanimation because he believed it would help bring peace and restore balance to the world. However, he did not revive Jiraiya because he felt that Jiraiya's death served a greater purpose in the grand scheme of things, and bringing him back would disrupt the natural order of things.

Working memory does have an influence on intelligence. It is considered a key component of cognitive functioning and is closely related to abilities such as problem-solving, reasoning, and learning. Individuals with higher working memory capacity tend to perform better on tasks that require complex thinking and cognitive flexibility, which are often associated with higher levels of intelligence. However, working memory is just one aspect of intelligence and does not solely determine overall intelligence levels. **

No, Edo Tensei is not simply a newly introduced term for the Jutsu of Reanimation from Dirty Earth. Edo Tensei is a specific technique used in the Naruto series, which allows the user to revive the dead and control them as puppets. It is a forbidden jutsu that was created by the legendary shinobi, Tobirama Senju. The Jutsu of Reanimation from Dirty Earth, on the other hand, is a different concept from a different series and does not have the same abilities or characteristics as Edo Tensei. **
