Inactivation of the dorsolateral periaqueductal gray matter impairs the promoting influence of stress on fear memory during retrieval
(Springer Heidelberg, 2019-11)
Exposure to stressful conditions induces long-lasting neurobiological changes in selected brain areas, which could be associated with the emergence of negative emotional responses. Moreover, the interaction of a stressful ...
Corticostriatal signatures of schadenfreude: Evidence from Huntington's disease
(B M J Publishing Group, 2018-01)
Schadenfreude - pleasure at others' misfortunes - is a multidetermined social emotion which involves reward processing, mentalising and perspective-taking abilities. Patients with Huntington's disease (HD) exhibit reductions ...
The threehundred: The structure and properties of cosmic filaments in the outskirts of galaxy clusters
(Oxford Univ Press Inc, 2021-03)
Galaxy cluster outskirts are described by complex velocity fields induced by diffuse material collapsing towards filaments, gas, and galaxies falling into clusters, and gas shock processes triggered by substructures. A ...
Orbitofrontal and limbic signatures of empathic concern and intentional harm in the behavioral variant frontotemporal dementia
(Elsevier Masson, 2016-02)
Perceiving and evaluating intentional harms in an interpersonal context engages both cognitive and emotional domains. This process involves inference of intentions, moral judgment, and, crucially, empathy towards others' ...
Improving Spatial Normalization of Brain Diffusion MRI to Measure Longitudinal Changes of Tissue Microstructure in the Cortex and White Matter
(John Wiley & Sons Inc, 2020-09)
Background: Fractional anisotropy (FA) and mean diffusivity (MD) are frequently used to evaluate longitudinal changes in white matter (WM) microstructure. Recently, there has been a growing interest in identifying ...
Alzheimer disease periventricular white matter lesions exhibit specific proteomic profile alterations
(Elsevier, 2013-01)
The white matter (WM) represents approximately half the cerebrum volume and is profoundly affected in Alzheimer's disease (AD). However, both the WM responses to AD as well as potential influences of this compartment to ...
Reduced functional connectivity within the primary motor cortex of patients with brachial plexus injury
(Elsevier, 2016-02)
This study aims at the effects of traumatic brachial plexus lesion with root avulsions (BPA) upon the organization of the primary motor cortex (M1). Nine right-handed patients with a right BPA in whom an intercostal to ...
Amyloid-β peptide remnants in AN-1792-immunized Alzheimer's disease patients: A biochemical analysis
(Amer Soc Investigative Pathology, Inc, 2006-12)
Experiments with amyloid-β (Aβ)-42-immunized transgenic mouse models of Alzheimer's disease have revealed amyloid plaque disruption and apparent cognitive function recovery. Neuropathological examination of patients ...
One Week of Motor Adaptation Induces Structural Changes in Primary Motor Cortex That Predict Long-Term Memory One Year Later
(Society for Neuroscience, 2011-08)
The neural bases of motor adaptation have been extensively explored in human and non-human primates. A network including the cerebellum, primary motor and the posterior parietal cortex appears to be crucial for this type ...
A novel pathogenic mechanism for cerebellar lesions produced by Solanum bonariense in cattle
(American Association of Veterinary Laboratory Diagnosticians, 2015-05)
Intoxication with Solanum bonariense in cattle causes cerebellar cortical degeneration with perikaryal vacuolation, axonal swelling, and death primarily of Purkinje cells, with accumulation of electron-dense residual storage ...
