Associative memory in chronic schizophrenia: a computational model
(Elsevier BV, 2003)We developed a computer model to simulate associative memory recall of patients with chronic schizophrenia. Model inputs consisted of words derived from normative data that differed in terms of connectivity and network ... -
Cerebral versus Ocular Visual Impairment: The Impact on Developmental Neuroplasticity
(Frontiers Media S.A., 2016)Cortical/cerebral visual impairment (CVI) is clinically defined as significant visual dysfunction caused by injury to visual pathways and structures occurring during early perinatal development. Depending on the location ... -
Cortico–Cortical Connections of Primary Sensory Areas and Associated Symptoms in Migraine
(Society for Neuroscience, 2016)Abstract Migraine is a recurring, episodic neurological disorder characterized by headache, nausea, vomiting, and sensory disturbances. These events are thought to arise from the activation and sensitization of neurons ... -
Decreased Cerebellar-Orbitofrontal Connectivity Correlates with Stuttering Severity: Whole-Brain Functional and Structural Connectivity Associations with Persistent Developmental Stuttering
(Frontiers Media S.A., 2016)Persistent developmental stuttering is characterized by speech production disfluency and affects 1% of adults. The degree of impairment varies widely across individuals and the neural mechanisms underlying the disorder and ... -
Differential psychophysiological interactions of insular subdivisions during varied oropharyngeal swallowing tasks
(Wiley Periodicals, Inc., 2014)Abstract The insula is a highly integrated cortical region both anatomically and functionally. It has been shown to have cognitive, social–emotional, gustatory, and sensorimotor functions. Insular involvement in both normal ... -
Predicting inter-hemispheric transfer time from the diffusion properties of the corpus callosum in healthy individuals and schizophrenia patients: A combined ERP and DTI study
(Elsevier BV, 2011)Background—Several theories of schizophrenia have emphasized the role of aberrant neural timing in the etiology of the disease, possibly as a consequence of conduction delays caused by structural damage to the white-matter ... -
Variational Bayesian causal connectivity analysis for fMRI
(Frontiers Media S.A., 2014)The ability to accurately estimate effective connectivity among brain regions from neuroimaging data could help answering many open questions in neuroscience. We propose a method which uses causality to obtain a measure ...
