Multiscale representations such as the wavelet transform are useful for many signal processing tasks. Graphs are flexible models to represent complex networks and a spectral graph wavelet transform (SGWT) has recently been developed as a generalization of conventional wavelet designs. Here we extend the SGWT to obtain a Parseval frame, which conserves energy in the transformed domain and makes the...

One of the basic principles underlying modern neuroscience is that of connectional specificity; that is, neurons in different regions of the brain do not form connections randomly but rather in a manner that facilitates the processing of information among regions with related functions. A full characterization of the connectional specificity of the human brain would require identifying all connections...
In this work, we apply the UNFOLD technique to a hybrid 3D-EPI sequence in order to accelerate image acquisition for fMRI studies. UNFOLD is used in the 3D slice encoding direction which directly doubles the temporal resolution. Combining UNFOLD with Partial Fourier acqusition further reduces the acquisition time for a whole brain volume from 2.4 seconds to 1 seconds. The sequence was tested on healthy...
