Researchers have identified brain regions where speech sounds are perceived with abstract meaning, independent of sensory input. The study found two left-hemisphere speech-processing regions that code speech at an abstract level.
A recent study on the burying beetle found that parents instinctively favor older offspring, leading to unequal growth rates among siblings. The researchers believe this bias is due to both increased survival value and dominance in younger siblings.
Researchers found that inducible nitric oxide synthase (iNOS) activation promotes mutagenic changes in DNA, leading to biliary carcinogenesis. NO generation was increased by inflammatory cytokines and suppressed by an iNOS inhibitor.
A study by Montreal Neurological Institute researchers found that tone-deaf individuals have a thicker cortex in regions involved in auditory and musical processing. This parallels the observed cortex thickness in dyslexia, suggesting abnormal neuronal migration or cell pruning during development may contribute to the disorder.
A study published in Personality and Social Psychology Bulletin found that people consistently favor the underdog to win, regardless of scenario. The researchers propose that this is because underdogs evoke a sense of fairness and justice, as well as the perception that they put forth more effort.
