Yakovlevian Torque
Yakovlevian torque (also known as occipital bending (OB)[1] or counterclockwise brain torque[2]) is the tendency of the right side of the human brain to be warped slightly forward relative to the left and the left side of the human brain to be warped slightly backward relative to the right.

Noticeable protrusions of the hemispheres, anteriorly and posteriorly, are observed, as well as differences in the widths of the frontal (F) and occipital (O) lobes. These protrusions produce imprints on the inner skull surface, known as petalia. A twisting effect is also observed, known as Yakovlevian torque, in which structures surrounding the right Sylvian fissure are âtorqued forwardâ relative to their counterparts on the left. The left occipital lobe is also splayed across the midline and skews the inter hemispheric fissure in a rightward direction.â
The Yakovlevian asymmetries were first published in 1976 entitled: Morphological cerebral asymmetries of modern man, and non-human primates Ann NY Acad. Sci. , 280, 349-366 by LeMay, M, & Kido, D.K.
Anyone else find their head and occlusion follow this pattern? Mine does.Â
Can expansion be related to our thinking/ cognition?
The left hemisphere represents reality to itself, labelling, listing, naming, categorising. Whereas the right hemisphere focuses on âthe between-nessâ, connections, relationships, or the whole.
If the right side less developed, think more in terms of overall picture, âthe whole,â or if less side narrower, think more in language, categories, details?Â
