Multiple frequency functional connectivity in the hand somatosensory network: An EEG study

To investigate the dynamics of communication within the primary somatosensory neuronal network.Multichannel EEG responses evoked by median nerve stimulation were recorded from six healthy participants. We investigated the directional connectivity of the evoked responses by assessing the Partial Directed Coherence (PDC) among five neuronal nodes (brainstem, thalamus and three in the primary sensorimotor cortex), which had been identified by using...
