Abstract

Cerebral hemispheres are mainly supplied by the ipsilateral carotid arteries. The influence of arterial asymmetry on handedness development has been cited but remains unclear. A recently published study suggests that hand preference is related to common carotid (CC) arterial asymmetry. This study investigates the relationship between the haemodynamic characteristics of the CC arteries and hand preference/proficiency using Doppler ultrasonography. Fifty participants (26 male, 24 female; mean age 2 ± 4.7) completed Edinburgh Handedness Inventory and Target Speed and Accuracy Tests to quantify their hand preference/proficiency. Participants were subjected to 10 min of supine rest prior to commencing ultrasound assessment. The CC arteries were visualized using GE Logic e ultrasound system with a 12L‐RS transducer. Peak‐systolic velocities, end‐diastolic velocities, and arterial cross sectional areas were measured. There was a significant difference in hand proficiency between body side and sexes in left‐and right‐handed participants (P value < 0.05). Hand preference/proficiency; however, was not influenced by the CC arteries peak‐systolic velocities, end‐diastolic velocities or cross sectional areas. No significant correlation between arterial flow and hand preference/proficiency was found. Further studies are needed to examine the lateral differences in the blood supply to the brain accounting for the effect of sample size, anatomical variations, and noncarotid sources of blood.
