Document Summary
E-reader 1: repetitive tms for treatment resistant depression: re- establishing connections. Brain connectivity and depression: significant dysfunction within distributed fronto-limbic networks: component regions demonstrate complex patterns of interconnectivity. Structural connectivity = anatomical connections of the brain which provide the structural architecture for communication between brain regions. Dwi (diffusion weighted imaging) measures the movement of water molecules in the brain over time. Functional connectivity = correlation of events in spatially separated brain regions over time: measured via functional imaging techniques (eeg, meg, pet, fmri); primary tool used: resting-state fmri low-frequency spontaneous oscillations in the. Bold signal are correlated in regions considered to be functionally connected: correlated regions organized into networks intrinsic connectivity networks (icns, subsume similar functions and remain coherent during activity and the resting state. Dysfunction within icns and abnormalities in anatomical connectivity associated with a number of psychological disorders.
