Thinking is invisible, so the icons for it have to be borrowed: a brain for the organ, a thought bubble for the process, a lightning bolt for the moment it lands. All three are here, and having them in one style lets a product show the sequence rather than one static symbol.

What is in the set
Brains rendered plainly and with electrical activity. Neurons and neural network structures. Thought bubbles combined with gears, lightning bolts and ideas. Innovation scenes such as inventors with blueprints and teamwork insight. Plus cognitive and study motifs.
Where these work best
AI and machine learning products, mental health and mindfulness apps, learning and memory tools, neuroscience material, and brainstorming features. Light bulb covers the idea metaphor; robot covers machine intelligence.
