Variability in hemispheric functional segregation phenotypes: A review and general mechanistic model

R Gerrits - Neuropsychology Review, 2024 - Springer
Many functions of the human brain are organized asymmetrically and are subject to strong
population biases. Some tasks, like speaking and making complex hand movements, exhibit …

Cerebral polymorphisms for lateralisation: Modelling the genetic and phenotypic architectures of multiple functional modules

C McManus - Symmetry, 2022 - mdpi.com
Recent fMRI and fTCD studies have found that functional modules for aspects of language,
praxis, and visuo-spatial functioning, while typically left, left and right hemispheric …

Comparing human and chimpanzee temporal lobe neuroanatomy reveals modifications to human language hubs beyond the frontotemporal arcuate fasciculus

Assessing the reliability of an online behavioural laterality battery: A pre-registered study

AJ Parker, ZVJ Woodhead, PA Thompson, DVM Bishop - Laterality, 2021 - Taylor & Francis
Studies of cerebral lateralization often involve participants completing a series of perceptual
tasks under laboratory conditions. This has constrained the number of participants recruited …

Left-handers are less lateralized than right-handers for both left and right hemispheric functions

LT Johnstone, EM Karlsson, DP Carey - Cerebral Cortex, 2021 - academic.oup.com
Many neuroscientific techniques have revealed that more left-than right-handers will have
unusual cerebral asymmetries for language. After the original emphasis on frequency in the …

[HTML][HTML] Let's face it: The lateralization of the face perception network as measured with fMRI is not clearly right dominant

I Thome, JCG Alanis, J Volk, C Vogelbacher… - NeuroImage, 2022 - Elsevier
The neural face perception network is distributed across both hemispheres. However, the
dominant role in humans is virtually unanimously attributed to the right hemisphere …

An updated investigation of the multidimensional structure of language lateralization in left-and right-handed adults: a test–retest functional transcranial Doppler …

ZVJ Woodhead, PA Thompson… - Royal Society …, 2021 - royalsocietypublishing.org
A previous study we reported in this journal suggested that left and right-handers may differ
in their patterns of lateralization for different language tasks (Woodhead et al. 2019 R. Soc …

[HTML][HTML] Inconsistent language lateralisation–Testing the dissociable language laterality hypothesis using behaviour and lateralised cerebral blood flow

AJ Parker, ZVJ Woodhead, DP Carey, MA Groen… - cortex, 2022 - Elsevier
Background Most people have strong left-brain lateralisation for language, with a minority
showing right-or bilateral language representation. On some receptive language tasks …

The validity and reliability of quantifying hemispheric specialisation using fMRI: Evidence from left and right handers on three different cerebral asymmetries

LT Johnstone, EM Karlsson, DP Carey - Neuropsychologia, 2020 - Elsevier
Neuroimaging has tremendous potential for quantifying hemispheric specializations.
However, the possibilities remain under-utilized, in part, given some of the complexities in …
