Superconducting nanowire single-photon detectors: Next big thing in blood flow measurement

Researchers developed a novel detector system using superconducting nanowire single-photon detectors to measure cerebral blood flow. The SNSPD-DCS system showed significant improvement in signal-to-noise ratio compared to conventional SPAD-based DCS, allowing for clearer detection of arterial pulses.

The music of silence: Imagining a song triggers similar brain activity to moments of mid-music silence

Researchers used EEGs to measure brain activity while musicians listened to or imagined Bach piano melodies, finding consistent patterns of neural activity during silent intervals. The study suggests that the brain reacts to both notes and silences of music, engaging in a continuous attempt to predict upcoming musical events.

Neurotransmitter levels predict math ability

Researchers found that higher GABA levels in young people were associated with greater math fluency, while lower glutamate levels were related to better math skills. In adults, the opposite was true: low GABA concentrations were linked to greater math fluency and high glutamate levels to poorer performance.

Scientists reverse age-related memory loss in mice

Researchers at the University of Cambridge and University of Leeds successfully reversed age-related memory loss in mice by manipulating the extracellular matrix of the brain. By restoring the balance of compounds known as chondroitin sulphates, they were able to restore neuroplasticity and alleviate memory deficits.

SUV39H2: A direct genetic link to autism spectrum disorders

A human variant of the SUV39H2 gene has been linked to autism spectrum disorders, causing cognitive inflexibility in mice and misregulated expression of genes related to brain development. The study suggests that histone methylation plays a crucial role in regulating gene expression, and its absence may lead to serious problems.
