Handedness asymmetry or RHA measured by a tapping task Abstract Introduction Biological research has shown that handedness is caused by a cerebral asymmetry in organisation of motor control. It is believed that physiological arousal may cause the release of neurotransmitters that affect the neuro-pathways involved in motor control. Due to hemispheric asymmetry the effect of these neurotransmitters will be released on the left hemisphere. This in theory changes the balance of motor control and a right hand advantage will be produced as the right hand is controlled by the left hemisphere. Being left handed I felt it would be interesting to examine whether this right hand advance is significant. One of the earliest studies into the different hemispheres of the brain was the 'split brain' study by Roger Sperry. He learnt that by cutting the 'Corpus callosum', (myelinated nerve fibres, which connects the left and right hemispheres of the brain), that...
