The Consortium on Language Asymmetry (COLA) is a group of research teams united by an interest in understanding language lateralisation in the brain. It was set up in 2018 with the aims of sharing knowledge, data and materials, and conducting collaborative experiments.
It is known that the left hemisphere of the brain is more active during language tasks in the large majority of individuals, but the causes and consequences of this lateralisation are still unknown. We are also interested in understanding what drives atypical lateralisation (right or bilateral), and whether this has any impact on language ability or lateralisation of other brain functions, such as visuospatial processing.
The majority of our research uses functional transcranial Doppler sonography (fTCD, or ‘Doppler’ for short). This non-invasive technique uses ultrasound waves to detect the speed of blood flow to the left and right sides of the brain. It is relatively cheap, portable and suitable for use in adults and children. Some COLA members also use functional Magnetic Resonance Imaging (fMRI), functional Near-Infrared Spectroscopy (fNIRS) or behavioural techniques to investigate lateralisation.
COLA members share a commitment to open science practises, and we welcome requests to join the consortium or to use our open datasets or stimuli.
