Cognition is biological information processing: taking in information, retaining memories, and adapting to the environment. Human cognition includes thought, imagination, intuition, creativity, and common sense, though how thoughts arise remains poorly understood. section 6.0 section 6.3
Cognition also appears in cellular activity. Cells sense and process changes, respond, and coordinate to maintain the body’s equilibrium. section 9.3
Immune-cell learning
When a measles virus infects a child, an immune cell develops an antibody response and adjusts the antibody to match the virus. The cell retains this learning in a gene that passes to its daughter cells. section 9.3
AI can recognize patterns and analyze data, but these abilities do not amount to human-like cognition. Human thought involves biological and biochemical processes, while current AI remains limited in creativity and in recognizing objects and scenes as people do. section 6.0 section 9.3
