Essentials in brain connectivity

Imaging Neuroscience is aiming to reveal functional changes, that is, changes in brain activity, and structural changes, which address changes in neuroanatomy. There is a growing interest in defining functional interactions of different brain regions based on the increased sensitivity and specificity of functional magnetic resonance imaging (fMRI). The present contribution is a brief overview of the trends in brain connectivity research driven by the development of several techniques derived from fMRI.
