Wavelet analysis for brain-function imaging

Wavelet analysis for brain-function imaging

The authors present a new algorithmic procedure for the analysis of brain images. This procedure is specifically designed to image the activity and functional organization of the brain. The authors' results are tested on data collected and previously analyzed with the technique known as in vivo optical imaging of intrinsic signals. The authors' procedure enhances the applicability of this techn...

Wavelet-Based Statistical Analysis versus SPM of Brain Imaging Data

Analysis of functional magnetic resonance imaging (fMRI) data of a block-based visual stimulation paradigm was comparatively performed by the discrete wavelet transform (DWT) in the wavelet domain and statistical parametric mapping (SPM) within the framework of the general linear model (GLM) [1]. The link is supported by the low-pass analysis filter of the DWT that can be similarly shaped to a ...

Using functional magnetic resonance imaging (fMRI) to explore brain function: cortical representations of language critical areas

Pre-operative determination of the dominant hemisphere for speech and speech associated sensory and motor regions has been of great interest for the neurological surgeons. This dilemma has been of at most importance, but difficult to achieve, requiring either invasive (Wada test) or non-invasive methods (Brain Mapping). In the present study we have employed functional Magnetic Resonance Imaging...
