Hemispheric Asymmetry in Neuroscience

Behavioral state-dependent lateralization of dorsal dentate gyrus c-Fos expression in mice

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.

A large-scale population study of early life factors influencing left-handedness

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.

Saccades and Handedness Interact to Affect Scene Memory

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

Right hemisphere superiority for executive control of attention

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

Human Handedness: Genetics, Microtubules, Neuropsychiatric Diseases and Brain Language Areas

This study identifies genome-wide significant genetic loci for handedness and links them to microtubule-related genes associated with brain lateralization and neurodevelopmental disorders.

Subtle left-right asymmetry of gene expression profiles in embryonic and foetal human brains

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.

Sex chromosome trisomies are not associated with atypical lateralisation for language

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.

Mapping Cortical Brain Asymmetry in 17,141 Healthy Individuals Worldwide via the ENIGMA Consortium

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.

Network-based asymmetry of the human auditory system

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.

Hemispheric lateralization of Heschl’s gyrus and amygdala subdivisions are involved in differentiating happy and sad acoustic emotion

The paper investigates how functional activation in Heschl’s gyrus and amygdala subdivisions differentiates between happy and sad acoustic stimuli, finding hemispheric lateralization patterns specific to sad emotions.
