Inside the Brain & Spine – are you left-handed or right-handed? Perhaps you write with one hand but play sport with the other. Have you ever wondered why? Genetics plays a role but your brain also ‘chooses’ which hand to use for different tasks. The motor cortex and parietal lobe coordinate to select the most efficient limb for the task…and you don’t even know it! Both hemispheres of the brain collaborate to perform complex activities like writing, playing sport and following directions – this is known as lateralisation. Guess that means we’re all a little bit ambidextrous!
