Handedness is related to neural mechanisms underlying hemispheric lateralization of face processing
2016
Scientific Reports
Preserved Fulltext
However, the neural mechanisms underlying differential hemispheric lateralization of face perception in right-and left-handers are largely unknown. ...
While the right-hemispheric lateralization of the face perception network is well established, recent evidence suggests that handedness affects the cerebral lateralization of face processing at the hierarchical ...
Third, high-frequency noise in the pupil size traces was suppressed using a sliding square window of 50 ms width. ...

In this review, we aim to decipher key issues of ipsilesional and contralesional hemispheric functioning allowing the foundations of effective neurorehabilitation strategies. ...
In moderate-to-severe stroke, neurological outcome is often poor, and little is known about the paths that enable either an efficient collaboration among hemispheres or, on the contrary, an antagonism ...
Those include the transient role of contralateral hemisphere in recovery of lateralized functions, the disparate recovery levels of highly lateralized functions such as language or motor function, and ...

As a secondary consequence of asymmetrical light experience, lateralized top-down mechanisms play a critical role in the emergence of hemispheric dominance. (2) Ontogenetic light experiences may affect ...
