Neuroscientists reveal how the brain can enhance connections

When the brain forms memories or learns a new task, it encodes the new information by tuning connections between neurons. MIT neuroscientists have discovered a novel mechanism that contributes to the strengthening of these ...

Tone of voice matters in neuronal communication

The dialogue between neurons is of critical importance for all nervous system activities, from breathing to sensing, thinking to running. Yet neuronal communication is so fast, and at such a small scale, that it is exceedingly ...

What birdsong tells us about brain cells and learning

Most scientists who study the brain believe that memories are stored through networks of synapses, or connections that form between neurons. Learning takes place as neurons form new connections and strengthen or weaken existing ...

New research could reduce the risk of sudden cardiac death

Around 26 million people worldwide suffer from heart failure, with more than 50 per cent dying suddenly most likely due to the spontaneous onset of a heart rhythm problem, known as an arrhythmia. The link between the electrical ...
