Deductive reasoning. Deductive reasoning links premises with conclusions. If all premises are true, the terms are clear, and the rules of deductive logic are followed, then the conclusion reached is necessarily true. Deductive reasoning (top-down logic) contrasts with inductive reasoning (bottom-up logic) in the following way: In deductive reasoning, a conclusion is reached reductively by applying general rules that hold over the entirety of a closed domain of discourse, narrowing the range under consideration until only the conclusion(s) is left. In inductive reasoning, the conclusion is reached by generalizing or extrapolating from, i.e., there is epistemic uncertainty. Note, however, that the inductive reasoning mentioned here is not the same as induction used in mathematical proofs – mathematical induction is actually a form of deductive reasoning.

Through his studies of the brain "on jazz," music-loving otolaryngologist Charles Limb aims to unravel the mind's secrets of creativity. By Nick Zagorski | Photo by Keith Weller David Kane had never played keyboard quite like this. Sure, the 53-year-old musician and composer had experienced his share of cramped recording studios and poorly tuned pianos during his 37-year career. But those inconveniences paled in comparison to this session.
Kane lay prostrate in an MRI tube, with a miniature electronic keyboard perched on his knees. "Physically, it wasn't too uncomfortable," he jokes today, "but for my creative space, it was horrible. " Three-dimensional surface projection of activations and deactivations associated with improvisation during jazz. "How do the legends, musicians like John Coltrane, get up on stage and improvise music for an hour or sometimes more? " Answering those questions appears daunting, as creativity may be the most enigmatic component of the human brain. Charles Limb: Your brain on improv. Top-down and bottom-up design. Top-down and bottom-up are both strategies of information processing and knowledge ordering, used in a variety of fields including software, humanistic and scientific theories (see systemics), and management and organization. In practice, they can be seen as a style of thinking and teaching.
A top-down approach (also known as stepwise design and in some cases used as a synonym of decomposition) is essentially the breaking down of a system to gain insight into its compositional sub-systems. In a top-down approach an overview of the system is formulated, specifying but not detailing any first-level subsystems. Each subsystem is then refined in yet greater detail, sometimes in many additional subsystem levels, until the entire specification is reduced to base elements. A top-down model is often specified with the assistance of "black boxes", these make it easier to manipulate.
