Moral judgement by the disconnected left and right cerebral hemispheres: a split-brain investigation

Moral judgement by the disconnected left and right cerebral hemispheres: a split-brain investigation

Owing to the hemispheric isolation resulting from a severed corpus callosum, research on split-brain patients can help elucidate the brain regions necessary and sufficient for moral judgement. Notably, typically developing adults heavily weight the intentions underlying others' moral actions, placing greater importance on valenced intentions versus outcomes when assigning praise and blame. Prio...

Word length and orthographic neighborhood size effects in the left and right cerebral hemispheres.

Previous studies have reported an interaction between visual field (VF) and word length such that word recognition is affected more by length in the left VF (LVF) than in the right VF (RVF). A reanalysis showed that the previously reported effects of length were confounded with orthographic neighborhood size (N). In three experiments we manipulated length and N in lateralized lexical decision t...

Disrupting the right prefrontal cortex alters moral judgement.

Humans daily face social situations involving conflicts between competing moral decision. Despite a substantial amount of studies published over the past 10 years, the respective role of emotions and reason, their possible interaction, and their behavioural expression during moral evaluation remains an unresolved issue. A dualistic approach to moral evaluation proposes that the right dorsolater...

Analysis of the Asymmetric Gene Expression between the Left and Right Hemispheres of Drosophila Brain

Studying the molecular mechanism of brain asymmetry can provide important clues to understand neurological diseases and psychiatric disorders related to brain lateralization. In this paper, asymmetric gene expression in the left/right hemispheres of Drosophila brain was genome-widely analyzed to help understand the molecular mechanism of brain asymmetry. Using microarray analysis of total RNAs ...
