Multimodal Image Coregistration and Partitioning—A Unified Framework
John Ashburner,Karl J. Friston +1 more
TL;DR: The basic idea is that instead of matching two images directly, one performs intermediate within-modality registrations to two template images that are already in register, and a least-squares minimization is used to determine the affine transformations that map between the templates and the images.

Increased glutamate in the hippocampus after galantamine treatment for Alzheimer disease
Jacob Penner,Raul Rupsingh,Matthew Smith,Jennie Wells,Jennie Wells,Michael Borrie,Michael Borrie,Robert Bartha +7 more
TL;DR: Increased Glu and the ratio of Glu to Cr measured by MR spectroscopy after galantamine treatment were associated with increased cognitive performance, which may be related to the action of galantamines as an allosteric potentiating ligand for presynaptic nicotinic acetylcholine receptors, which increases glutamatergic neurotransmission.
Procrustean solution of the 9-parameter transformation problem
TL;DR: In this paper, the Procrustean matching bed is employed to provide direct solution to the 9-parameter transformation problem inherent in geodesy, navigation, computer vision and medicine.
Bilateral thalamic gray matter changes in patients with restless legs syndrome.
Thorleif Etgen,Bogdan Draganski,Carolin Ilg,Michael Schröder,Michael Schröder,Peter Geisler,Göran Hajak,Ilonka Eisensehr,Dirk Sander,Arne May +9 more
TL;DR: This is the first demonstration of structural changes in the brain of patients with idiopathic restless legs syndrome, and changes in thalamic structures are either involved in the pathogenesis of RLS or may reflect a consequence of chronic increase in afferent input of behaviorally relevant information.
Decreased cerebral activation during CPT performance: structural and functional deficits in schizophrenic patients.
Pilar Salgado-Pineda,Carme Junqué,Pere Vendrell,Immaculada Baeza,Núria Bargalló,Carles Falcon,Miquel Bernardo +6 more
TL;DR: Three regions involved in attentional processes showed both structural and functional deficits: the thalamus, the anterior cingulate and the inferior parietal, which suggest that these regions may be involved in the attentional deficit in schizophrenia.
A voxel-based morphometric study of nondemented adults with Down Syndrome.
TL;DR: The utility of the VBM technique for investigating the neuroanatomy of DS demonstrates the utility of classic region-of-interest-based morphometry, which was used on 19 nondemented individuals with DS and 11 age-matched controls.

Spatial registration and normalization of images
Karl J. Friston,John Ashburner,Chris D. Frith,Jean-Baptiste Poline,Jon D. Heather,Richard S. J. Frackowiak +5 more
TL;DR: A general technique that facilitates nonlinear spatial (stereotactic) normalization and image realignment is presented that minimizes the sum of squares between two images following non linear spatial deformations and transformations of the voxel (intensity) values.

Rapid automated algorithm for aligning and reslicing PET images.
TL;DR: A computer algorithm for the three-dimensional alignment of PET images is described that relies on anatomic information in the images rather than on external fiducial markers and can be applied retrospectively, during acquisition, to reposition the scanner gantry and bed to match an earlier study.

3D statistical neuroanatomical models from 305 MRI volumes

- 31 Oct 1993
TL;DR: The authors have collected over 300 MRI volumetric datasets from normal individuals and transformed these datasets into stereotaxic space using a 3D linear re-sampling algorithm, and generated a series of statistical measures which express this population nonlinear variability in the form of parametric volumes.

TL;DR: The results indicate that retrospective techniques have the potential to produce satisfactory results much of the time, but that visual inspection is necessary to guard against large errors.
