Cracking the code of the extracellular matrix

Despite evidence for a role in plasticity and other crucial functions, many neuroscientists still view these proteins as “brain goop.” The field needs technical advances and a shift in scientific thinking to move beyond this outdated perspective.

Neurons making memories shush their neighbors

When neurons strengthen their synapses, they “infect” surrounding cells with a virus-like protein to weaken those cells’ excitatory connections, according to a new preprint.
