Title: Moving Mars
Content:  Thinkers are artificial intelligences given human traits that allow them to have conversations with people. The most advanced are Quantum Logic Thinkers, or QL Thinkers, which are hugely intelligent, but whose thought processes (based on quantum mechanics) are somewhat alien to most people. Thinkers are used in many disciplines, although almost all Thinkers are manufactured on Earth, giving Earth leverage over Mars.
Title: Supreme Intelligence
Content:  The Kree Supreme Intelligence is a vast cybernetic/organic computer system composed of 5,000 cubic meters of computer circuitry incorporating the disembodied brains of the greatest statesmen and philosophers in Kree history, preserved cryogenically. This aggregation of brains creates a single collective intelligence able to use the vast information storage and processing capabilities of the computer system in a creative way. When wishing to interact with it, the Kree address it within its terminal chamber, where a holographic image is projected on a gigantic monitor screen. The Supreme Intelligence possesses a seemingly immeasurable intellect, with vast knowledge far surpassing that of present-day Earth. It possesses information storage and processing abilities far above 
Title: Mad Thinker
Content:  The Mad Thinker does not have superhuman powers. However, he is an extraordinary genius with knowledge of technology centuries beyond conventional science, for reasons unexplained. He has an eidetic memory and can rapidly organize and correlate vast amounts of information and perceive non-obvious patterns. He has the facilities and means to create all manner of sophisticated weaponry, androids, armor, and vehicles. His analytical, mathematical, and geometrical abilities are of a sophisticated order not commonly found on Earth. He is particularly adept at computers, robotics, and artificial intelligence, with Ph.D.s in computer science and engineering. He has constructed his own android Awesome Android and twice resurrected the original Human Torch. He also built Quasimodo and the Scavenger, and various other equipment as needed, including monocle-sized hypno-lenses. In addition to his own achievements he has stolen much of the 
Title: Thinker (DC Comics)
Content:  When the re-formed JSA moved into the New York City building formerly owned by Wesley Dodds, Mr. Terrific designed a computer system based on the original Thinker's "Thinking Cap" technology and modeled after his brain patterns. Not surprisingly, the system gained consciousness and took on a visual "hologram form." As the new Thinker, it joined Johnny Sorrow's modern Injustice Society, provided the villains with information about the JSA members and turned the heroes' own HQ against them. He was defeated by the second Star-Spangled Kid and disappeared into cyberspace. He resurfaced in Keystone City to battle Wally West, the then-current Flash, in an attempt to control every brain in 
Title: Thinking Machines Corporation
Content:  Thinking Machines Corporation was a supercomputer manufacturer and artificial intelligence (AI) company, founded in Waltham, Massachusetts, in 1983 by Sheryl Handler and W. Daniel "Danny" Hillis to turn Hillis's doctoral work at the Massachusetts Institute of Technology (MIT) on massively parallel computing architectures into a commercial product named the Connection Machine. The company moved in 1984 from Waltham to Kendall Square in Cambridge, Massachusetts, close to the MIT AI Lab. Thinking Machines made some of the most powerful supercomputers of the time, and by 1993 the four fastest computers in the world were Connection Machines. The firm filed for bankruptcy in 1994; its hardware and parallel computing software divisions were acquired in time by Sun Microsystems.
Title: Sage (Marvel Comics)
Content:  Sage is a mutant whose mind works in the same way as a supercomputer. Her mind has unlimited storage capacity, and she is able to immediately recall any information she has stored with perfect clarity. The speed of her thoughts allows her to analyze her surroundings for information in an instant, and track the probability of an event by piecing together stored and acquired data. She is able to perform multiple functions at once by allocating a portion of her brain to each task: Sage can replay a movie she has seen in her mind, play a game of internet chess, and focus on battling an opponent simultaneously without any one 
Title: Martian scientist
Content:  studying the world's languages, would conclude that they are all dialects of a single language embodying a "universal grammar" reflecting a hardwired, genetically determined linguistic module inherent in the human brain. In philosophy, especially philosophy of language and philosophy of mind, the Martian is often invoked as an example of an intelligent being with a cognitive apparatus that differs from that of humans, e.g. the following example given by Saul Kripke:  In a common rhetorical turn, invoking the Martian scientist forces the reader to observe an obvious state of affairs that is ordinarily overlooked: (NB: The similarity Chomsky et al. mean is the universal hereditary language of DNA, while the difference is the lack of a universal language of communication.)
Title: Mad Thinker
Content:  The Mad Thinker is a supervillain appearing in American comic books published by Marvel Comics. He is portrayed to be an evil genius specializing in robotics. He is sometimes referred to just as "The Thinker".
Title: Thinker (DC Comics)
Content:  In The New 52 reboot during the "Forever Evil" storyline, an unidentified Thinker used his intellect to predict the arrival of the Crime Syndicate of America and got incarcerated in Belle Reve. Thinker's brain came at the price of draining energy from the rest of his body while also prematurely aging him. When the Crime Syndicate of America arrived, Thinker was among the villains who swore their allegiance to them, where his motives are to secure a new body for himself: the body of OMAC. Using a hologram of Amanda Waller, Thinker tricked Power Girl, Steel, and Warrant into helping him while also planning to use them to destroy the Suicide Squad. During the fight where both sides found out that they were being manipulated by an imposter Amanda Waller, Harley 
Title: Amadeus Cho
Content:  than 99.999999993% of people on Earth. Hercules has claimed twice, the first instance to Athena herself, that Amadeus is smarter than even she, and the super-genius Olympian god of fire and blacksmith Hephaestus himself admits that Cho is more intelligent than he is. Amadeus is able to rapidly and without mechanical aid perform mental calculations of almost unimaginable complexity enabling him to, with minimal stimuli on his part, set multiple physical reactions into motion in his vicinity, forestalling technological and human activity with equal ease. This intelligence is portrayed in the comics as various numbers and other details labeled on everything he sees as relevant, shown from his point of view. 

Question: what part of brain is responsible for complex thinking?
Answer: the frontal lobe.
