How does coffee affect a sleeping brain?
How does coffee affect a sleeping brain?
Coffee can help you stay awake. But what does caffeine actually do to your brain once you're asleep? Using AI, a team of researchers has an answer: it affects the brain's "criticality". Caffeine is not only found in coffee, but also in tea, chocolate, energy drinks and many soft drinks, making it one of the most widely consumed psychoactive substances in the world.

Study suggests we don’t just hear music, but ’become it’ 
An international study co-authored by McGill psychologist Caroline Palmer suggests our brains and bodies don't just understand music, they physically resonate with it. These discoveries, based on findings in neuroscience, music, and psychology, support Neural Resonance Theory (NRT). NRT maintains that rather than relying on learned expectations or prediction, musical experiences arise from the brain's natural oscillations that sync with rhythm, melody and harmony.

Guinea pigs: a promising animal model to study the human embryo
CRCHUM researchers reveal that the guinea pig pre-implantation embryo is very similar to the human embryo, spurring a better understanding of infertility and early human development. The first few days of a human embryo's development, known as pre-implantation, are important. It's when the first cells are formed, and these decide if the embryo can survive, how it will implant in the womb and how the tissues of the fetus will develop.

What links cannabis use and psychosis? Researchers point to the brain’s dopamine system
'Our findings could help doctors and mental health professionals better educate patients about the potential risks of frequent cannabis use' A McGill University-led study found that people with cannabis use disorder (CUD) had elevated dopamine levels in a brain region associated with psychosis. "This could help explain why cannabis use increases the risk of hallucinations and delusions, key symptoms of schizophrenia and other psychotic disorders," said first author Jessica Ahrens, a PhD candidate in McGill's Integrated Program in Neuroscience.
