A black brain silhouette packed with a maze of multicoloured circuit traces, and a line-art head in profile whose brain is outlined in red, sprouting a lightbulb, a target and arrows.

Brain within Medicine & Health
Anatomy covers the whole body and Health the everyday side of care. Brain narrows it down to one organ, drawn either as a medical diagram or as a symbol for thinking.
The circuit brain
Dark and dense, with thin neon-like traces: a natural fit for anything about artificial intelligence, neural networks or a cybersecurity talk. It stays readable when shrunk to an icon.
The idea head
Open, airy and at home in training materials: creativity, goal setting, a problem-solving workshop. The arrows point outward, so leave room around it for text labels.
