New program offers $35K grants to study ‘profound autism’

People who have ‘profound autism’ — those with severe intellectual disability, limited communication abilities or both — tend to be excluded from research. The Autism Science Foundation seeks to change that.

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 The field needs technical advances and a shift in scientific thinking to move beyond this outdated perspective.
