Bilingualism makes the brain more efficient, especially when learned at a young age

Researchers found increased whole-brain connectivity in bilingual participants, particularly those who learned their second language early in life. This increased connectivity was stronger between the cerebellum and left frontal cortex, indicating a more efficient brain organization in terms of functional connectivity.

Recreating a hallmark of Parkinson's disease in human neurons

Researchers create Lewy bodies in living dopaminergic neurons using human stem cells and find that immune challenge is crucial for their formation. The study identifies a previously unknown link between the immune system and neurological disease, suggesting that genetic predisposition may not be necessary for Parkinson's development.

The power of face time: Insights from zebra finch courtship

Researchers at McGill University found that zebra finches deprived of early social experiences can still form strong bonds with a partner later in life. Female finches developed a preference for their partner's song only when they lived together, suggesting quality time is essential for forming strong bonds.
