Hemispheric Asymmetry in Neuroscience

The paper investigates the relationship between hemi-face dominance in emotional expression and cerebral white matter asymmetries in healthy participants.

This paper reviews hippocampal lateralization in rodents and proposes a discrete-continuous hypothesis for spatial memory and navigation.

The paper shows that the Leask and Crow method for analyzing laterality-performance relationships produces artifacts due to nonlinear dependencies, suggesting alternative approaches may be more reliable.

The paper investigates genetic factors influencing planum temporale asymmetry and finds limited genetic links to neurodevelopmental disorders, intelligence, or educational attainment.

The paper examines hemispheric asymmetries in EEG and fMRI related to approach and avoidance behavior, finding no significant links to eating behavior or BMI.

The paper examines age-related differences in brain asymmetry during memory retrieval using fMRI and finds no evidence for compensatory contralateral over-activation in older adults.

The paper deconstructs the laterality index in fMRI to improve language lateralisation classification in epilepsy patients, achieving high accuracy in predicting lateralisation and Wada test results.

This study reanalyzes the genetic basis of hand preference using UK Biobank data, finding no support for previously reported variants but identifying a significant association with the MAP2 gene.

The paper maps functional hemispheric asymmetries in the human brain, identifies four functional axes, and links lateralisation to reduced inter-hemispheric connectivity.

This study uses functional transcranial Doppler sonography to test if language lateralisation varies across tasks, finding that most individuals show a single lateralised factor while a minority show dissociated asymmetry.

This study examines lateralized c-Fos expression in the mouse dentate gyrus during different behaviors, finding left-lateralization during object exploration and no difference during wheel running.

This study examines early life factors influencing left-handedness using UK Biobank data, finding weak heritability and significant effects of birthweight, season of birth, and other factors, but limited predictive power overall.

This study shows that saccades before scene working memory reduce memory accuracy, especially for inconsistent-handers, while saccades before recognition have smaller effects.

This study shows right hemisphere superiority in executive control of attention, dependent on alerting and orienting functions, using a modified Attentional Network Test.

The paper examines gene expression asymmetry in human embryos and fetuses, finding structure-specific transcriptomic laterality that correlates with age-related changes but not consistent left-right orientation.

This study investigates whether sex chromosome trisomies (SCTs) are associated with atypical language lateralization and finds no evidence of reduced left hemisphere bias for language.

The paper analyzes cerebral cortical asymmetry in 17,141 healthy individuals, finding widespread hemispheric and regional asymmetries, associations with sex, age, brain size, and heritability.

The paper shows that the right auditory cortex is more integrated in the brain network, enabling more efficient communication, with this asymmetry explained by diffusive communication mechanisms.
