Intervention Models in Functional Connectivity Identification Applied to fMRI
Intervention Models Functional Connectivity Identification fMRI
2009/9/8
Recent advances in neuroimaging techniques have provided precise spatial localization of brain activation applied in several neuroscience subareas. The development of functional magnetic resonance ima...
The Connectivity of the Human Pulvinar: A Diffusion Tensor Imaging Tractography Study
the Human Pulvinar Imaging
2009/9/4
Previous studies in nonhuman primates and cats have shown that the pulvinar receives input from various cortical and subcortical areas involved in vision. Although the contribution of the pulvinar to ...
Connectivity-Based Parcellation of the Cortical Mantle Using q-Ball Diffusion Imaging
Imaging the Cortical Mantle
2009/9/4
This paper exploits the idea that each individual brain region has a specific connection profile to create parcellations of the cortical mantle using MR diffusion imaging. The parcellation is performe...
Exploring the Anatomical Basis of Effective Connectivity Models with DTI-Based Fiber Tractography
Fiber Tractography Anatomical
2009/9/4
Diffusion tensor imaging (DTI) is considered to be a promising tool for revealing the anatomical basis of functional networks. In this study, we investigate the potential of DTI to provide the anatomi...
Effect of neural connectivity on autocovariance and cross covariance estimates
neural connectivity autocovariance and cross covariance estimates
2010/2/26
It is demonstrated that the potentials recorded from a monopolar electrode surrounded by dipole sources in a uniform medium are predominantly due to activity in neural structures far from the electrod...
