In the 1960s and 1970s, Roger Sperry and his student Michael Gazzaniga conducted landmark split-brain research, most famously reported in Sperry, 1968 and Gazzaniga, Bogen & Sperry, 1965, showing that when the corpus callosum is severed to treat severe epilepsy, the brain’s hemispheres can operate with striking independence, each possessing distinct perceptual and cognitive styles. Their elegant behavioural experiments revealed that the left hemisphere specialises in language and analytical reasoning while the right excels in spatial and holistic processing, a discovery that reshaped neuroscience and psychology by demonstrating the brain’s modular yet cooperative architecture. This work offers profound inspiration for personal wellbeing, reminding us that our minds contain diverse strengths that thrive through integration rather than competition, and it supports societal health by encouraging empathy for neurological differences and promoting educational, clinical, and policy approaches that honour the variety of human cognitive profiles. In Christianity we celebrate the rich variety of creation, including the neurodiversity seen in humans. When people live and work together with appreciation of each one’s unique make-up and gifting, good things happen. The Psalmist puts it like this: “Behold, how good and how pleasant it is for brethren to dwell together in unity! It is like the precious oil upon the head, running down on the beard, the beard of Aaron, running down on the edge of his garments. It is like the dew of Hermon, descending upon the mountains of Zion; For there the Lord commanded the blessing -

life forevermore!” (Psalm 133:2-3).
