News

  • Volumetric version of graynet is available now - check here

Overview

Individualized single-subject networks from T1-weighted magnetic resonance imaging (MRI) features such as:

  • Cortical thickness.
  • Gray matter density.
  • Subcortical morphometric features.
  • Gyrification and curvature.

Applicable for whenever network-level features are useful, among which common use cases are:

  • Biomarker development.
  • Brain-behaviour relationships (e.g. for the diagnosis and prognosis of many brain disorders such as Alzheimer's, Parkinson's, Schizophrenia and the like).
  • Aging (changes in network properties over age and their relations to other variables).
