We
present version 2.0 of piconmat.com, a freely-available web-based system for
exploring connectivity strengths between cortical and subcortical regions in
a database of individuals. Connectivity strength is computed using diffusion
MRI and probabilistic tractography. Version 2.0 is a significant update:
connectivity strengths are presented in an interactive connectivity matrix
and controls allow the user to study connectivity in individuals who meet
certain criteria (e.g., right-handed males aged 25-50), and connectivity
strengths for individuals belonging to different groups can be visually and
quantitatively compared (e.g., right-handed males vs. females).
