These networks never work in isolation but become more powerful the more integrated they are.
Let's start with the core elements of the Design Thinking process: 1. Empathy 2. Define 3. Ideation 4. Prototyping 5. Test
Empathy uses our feelings to understand a need. We then use our emotional intelligence and logic to articulate the need. (Default & Executive Networks?)
Ideation is filled with jostling "what if" questions that continually bounce off of each other until they synthesize down to a concept. (Salience & Default Networks?)
Prototyping requires a lot of logic as well hacking (Executive & Salience Networks?)
Testing involves logical analysis as well as empathetic perception (Executive Control & Default Network?)
