Handedness is related to neural mechanisms underlying hemispheric lateralization of face processing

Stefan Frässle, Sören Krach, Frieder Michel Paulus, Andreas Jansen
2016 Scientific Reports  
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.  ...

Functional Weight of Somatic and Cognitive Networks and Asymmetry of Compensatory Mechanisms: Collaboration or Divergency among Hemispheres after Cerebrovascular Accident?

Hélène Viruega, Manuel Gaviria
2021 Life  
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  ...

Functional and structural comparison of visual lateralization in birds – similar but still different

Martina Manns, Felix Ströckens
2014 Frontiers in Psychology  
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  ...  Functional lateralizations likely rely on structural left-right differences in intra-and interhemispheric connectivity patterns that develop in tight gene-environment interactions.  ...  Most humans show a dominance of the left hemisphere for the production and perception of language (Flöel et al., 2005; Bethmann et al., 2007) .  ...

Anticlockwise or clockwise? A dynamic Perception-Action-Laterality model for directionality bias in visuospatial functioning

A.K.M. Rezaul Karim, Michael J. Proulx, Lora T. Likova
2016 Neuroscience and Biobehavioral Reviews  
We call this model the 'Perception-Action-Laterality' (PAL) hypothesis.  ...  In support of PAL, we propose another model explaining the origins of the biases -how the neurogenetic factors and the cultural factors interact in a biased competition framework to determine the direction  ...  Likova is supported with a grant by the National Eye Institute at the National Institute of Health (R01EY024056), and this article was prepared with a support from the EPSRC (EP/J017205/1) to Michael J  ...

Olga Holtmann, Maximilian Bruchmann, Constanze Mönig, Wolfram Schwindt, Nico Melzer, Wolfgang H. R. Miltner, Thomas Straube
2020 Frontiers in Psychology  
The present study provides the first behavioral evidence of hemispheric lateralization of a specific emotion in the human brain, and contributes to neurobiological models of disgust.  ...  These findings propose a left-hemispheric basis of disgust, potentially due to asymmetrical representations of autonomic information in the human forebrain.  ...  ACKNOWLEDGMENTS All authors appreciate the patients' contribution to this work und would like to thank them and their families for participation in this study.  ...

Age-Related Changes in Hemispheric Organization [chapter]

Sander Daselaar, Roberto Cabeza
2004 Cognitive Neuroscience of Aging  
In fact, the most consistent finding in functional neuroimaging studies of cognitive aging is a reduction in the lateralization of prefrontal activations.  ...  The goal of this chapter is to address this disconnection and to link the topic of lateralization and aging to general issues regarding hemispheric organization.  ...  If this interhemispheric inhibition mechanism is impaired in older adults, for example because of callosal decline, then the activity in the less relevant hemisphere would not be extinguished and would  ...
