Lesley J. Rogers
University of New England (Emeritus Professor, per Routledge)
Lesley J. Rogers studies brain and behavioural lateralization. Routledge’s author biography for The Twofold Brain, checked on September 17, 2026, identifies her as Emeritus Professor at the University of New England. It credits her with discovering asymmetry in chick brain and behaviour and the importance of embryonic light exposure in its development. It also describes research across vertebrate and invertebrate species, including eye and hand preferences in primates.
Rogers co-authors The Twofold Brain with Giorgio Vallortigara. Routledge lists a first edition with copyright 2027 and 116 pages. Its subtitle is Exploring Fundamental Questions about Brain Lateralization. The contents include a chapter asking whether the two brain halves have separate and independent consciousness. The publisher material does not establish the authors’ answer.
Her lateralization research provides a basis for distinguishing functional specialization from conscious unity. Evidence that two sides perform different tasks does not alone establish two experiencing subjects. This is the distinction used in this site’s coverage, rather than a philosophical position attributed to Rogers.
