We obtained a 'consensus' partial coherence (cPCOH) by repeating this approach for several random aggregations of channels (permutations) and only accepting those activations in time and frequency with  ...  To address this challenge, we developed a new method that randomly aggregated channels into a smaller number of effective channels on which the calculation of partial coherence was based.  ...  Model dataset To test and compare the performance of coherence, pseudoinversebased partial coherence and consensus-based partial coherence we used a model that resembled the recorded signals and task structure  ...

Conclusions: A new cell-based treatment of AD and other neurodegenerative diseases by local delivery of NGF to targets in the brain was tested in an open-label Phase 1b clinical study.  ...  Optical imaging of ES is an exciting approach to mapping cortical circuitry. Future studies will examine plasticity in these stimulated neuronal networks. Supported by NIH R01NS-44375.  ...  Intra-operative evaluation of time-varying inter-hemispheric EEG coherence may be useful in monitoring the physiological effect of corpus callsotomy.  ...

2017 Stereotactic and Functional Neurosurgery  
Modeled lesions were used as seed regions for deterministic tractography on an 842-subject diffusion data template from HCP in order to identify involved connectomic networks.  ...  Methods: A segmentation of the ALIC based on frontal structural connectivity was generated using connectivity-based seed classification on 40 control subjects from the Human Connectome Project (HCP) (Figure  ...  This study highlights the role of unique structural changes in TN and structural brain imaging towards a more objective definition of neuropathic pain disorders.  ...
