Oscar Forrester
Very Big Brain is written by Oscar Forrester, a researcher and writer with a long-standing fascination with how the brain works. Oscar spent several years working in hospital IT, including on infection control systems, and grew up in a household shaped by medicine — his father was a physician and his mother a registered nurse. He is not a clinician himself, and nothing on this site should be taken as medical advice. What he brings instead is a rigorous, source-first approach to research, honed over two decades of writing (he’s authored numerous published books, primarily on software development), and a genuine curiosity about the science of cognition. Mr. Forrester strives to present complex topics in a clear and engaging manner, making it easy for you to understand and apply the knowledge to your daily life.
