Using voxel-based morphometry to map the structural changes associated with rapid conversion in MCI: A longitudinal MRI study
Discrimination between Alzheimer Dementia and Controls by Automated Analysis of Multicenter FDG PET
A new diagnostic indicator of FDG PET scan abnormality, based on age-adjusted t statistics and an automated voxel-based procedure, is presented and validated in a large data set comprising 110 normal…
In Vivo Mapping of Gray Matter Loss with Voxel-Based Morphometry in Mild Alzheimer's Disease
This study has mapped gray matter density by means of voxel-based morphometry on T1-weighted MRI volume sets in 19 patients with mild AD and 16 healthy subjects of similar age and gender ratio and report highly significant clusters of gray matter loss with almost symmetrical distribution.
The structural components of music perception. A functional anatomical study.
Activations preferentially in the left hemisphere for familiarity, pitch tasks and rhythm, and in the right hemisphere for the timbre task are found, suggesting a role for this cerebral region in the processing of sequential sounds.

It is demonstrated that autobiographical amnesia varies according to the nature of the memories under consideration and the locus of cerebral dysfunction, in the light of the two competing models of long-term memory consolidation and recent conceptions of autobiographical recollection.
Autobiographical memory, autonoetic consciousness, and self-perspective in aging.
Age-related differences were found for the specificity and spontaneity of memories and the phenomenal experience of remembering and the data support the view that older participants can subjectively "travel back in time" to relive personal events in the most distant past better than those in the recent past.
Voxel-based mapping of brain gray matter volume and glucose metabolism profiles in normal aging
Episodic and semantic remote autobiographical memory in ageing
Assessment of age effects on autobiographical memory according to the length of the retention interval, taking into account the episodic and semantic components revealed that episodic recall deteriorated more with age and retention interval than semantic recall.
What does transient global amnesia really mean? Review of the literature and thorough study of 142 cases.
This paper reported 142 personal TGA cases, and suggested the existence of different groups of TGA patients, on the basis of a hierarchical cluster analysis, which revealed that in women, episodes are mainly associated with an emotional precipitating event, a history of anxiety and a pathological personality.

It is found that hippocampal atrophy is specifically related to cingulum bundle disruption, which is in turn highly correlated to hypometabolism of the posterior cingulate cortex but also of the middle cingulates gyrus, thalamus, mammillary bodies, parahippocampal gyrus and hippocampus, as well as the right temporoparietal associative cortex.
