neurons

The cerebral cortex, the brain’s outermost region responsible for higher cognitive functions, depends on a highly ordered, layered structure. Its proper development requires newly generated neurons to migrate to precise locations at specific times.  Brain synapses and neurons – artistic interpretation.

It allows us to flexibly react to formerly threatening situations once the

But the brain is not static; neurons continually adjust the strength of their connections, a property called “synaptic plasticity”, and this flexibility is the basis of memory and learning. But aging and Alzheimer’s disrupt

Researchers at the University of Geneva (UNIGE) have discovered that neurons located in the
