Less Strongly Lateralized. In a standard brain, the left cerebral hemisphere is larger than the right. A Less Strongly Lateralized (one-sided) brain generally has greater hemispheric symmetry, a larger corpus callosum and greater inter-hemispheric communication, than the asymmetric norm. Anomalous Cerebral Laterality is a special case of a LSL brain — one that is the result of anomalous hormonal influences in utero. See text, Chapter 4.
