Machine learning for filtering out false positive grey matter atrophies in single subject voxel based morphometry: A simulation based study
(Elsevier Science, 2020-11)
Single subject VBM (SS-VBM), has been used as an alternative tool to standard VBM for single case studies. However, it has the disadvantage of producing an excessively large number of false positive detections. In this ...
Cambios estructurales cerebrales en epilepsia generalizada idiopática identificados por análisis de imágenes de resonancia magnética automatizados.
(Medicina (Buenos Aires), 2019-05)
Cerebral structural changes in generalized idiopathic epilepsy identified by automated magnetic resonance imaging analysis. The purpose of this study was to combine two automated methods of magnetic resonance imaging (MRI) ...
Neurocognitive signatures of phonemic sequencing in expert backward speakers
(Nature Publishing Group, 2020-06)
Despite its prolific growth, neurolinguistic research on phonemic sequencing has largely neglected the study of individuals with highly developed skills in this domain. To bridge this gap, we report multidimensional ...
Fatigue in multiple sclerosis is associated to multimodal interoceptive abnormalities
(Sage Publications Ltd, 2019-11)
Background: Fatigue ranks among the most common and disabling symptoms in multiple sclerosis (MS). Recent theoretical works have surmised that this trait might be related to alterations across interoceptive mechanisms. ...
Evaluating the reliability of neurocognitive biomarkers of neurodegenerative diseases across countries: A machine learning approach
(Academic Press Inc Elsevier Science, 2020-03)
Accurate early diagnosis of neurodegenerative diseases represents a growing challenge for current clinical practice. Promisingly, current tools can be complemented by computational decision-support methods to objectively ...
Multimodal neurocognitive markers of naturalistic discourse typify diverse neurodegenerative diseases
(Oxford Univ Press Inc, 2021-12)
Neurodegeneration has multiscalar impacts, including behavioral, neuroanatomical, and neurofunctional disruptions. Can diseasedifferential alterations be captured across such dimensions using naturalistic stimuli? To address ...
Structural neuroimaging of social cognition in progressive non-fluent aphasia and behavioral variant of frontotemporal dementia
(Frontiers Research Foundation, 2013-08)
Social cognition impairments are pervasive in the frontotemporal dementias (FTD). These deficits would be triggered by (a) basic emotion and face recognition processes as well as by (b) higher level social cognition (e.g., ...
VBM sensitivity to localization and extent of mouse brain lesions: A simulation approach
(Elsevier Ireland, 2020-11)
Background and objectives: Voxel-based morphometry (VBM) is a popular neuroimaging technique, used to detect and quantify morphological differences in brain tissues between groups. Widely used in human studies, VBM approaches ...
Your perspective and my benefit: multiple lesion models of self-other integration strategies during social bargaining
(Oxford University Press, 2016-11)
Recursive social decision-making requires the use of flexible, context-sensitive long-term strategies for negotiation. To succeed in social bargaining, participants' own perspectives must be dynamically integrated with ...
