The Anatomy of Category-specific Object Naming in Neurodegenerative Diseases
Neuropsychological studies suggest that knowledge about living and nonliving objects is processed in separate brain regions. However, lesion and functional neuroimaging studies have implicated different areas. To address this issue, we used voxel-based morphometry to correlate accuracy in naming line drawings of living and nonliving objects with gray matter volumes in 152 patients with various ...
متن کاملSound Symbolic Naming for Moving Objects
Sound symbolism is the non-arbitrary use of speech sounds to convey meaning. For example, we tend to mark large objects with back vowels, e.g., /u/ in ”huge,” and small objects with front vowels, e.g., /i/ in ”tiny.” Previous research into sound symbolic naming has suggested that an object’s motion is considered when naming the object. We report results from two experiments in which participant...
متن کاملAstrocytes in neurodegenerative disease.
Astrocytes contribute to the maintenance of the health and function of the central nervous system (CNS). Thus, it is not surprising that these multifunctional cells have been implicated in the onset and progression of several neurodegenerative diseases. The involvement of astrocytes in the neuropathology of these diseases is likely a consequence of both the loss of normal homeostatic functions ...
متن کاملBioinformatics in Neurodegenerative Disease
The brain response to the original viral insult is a crucial aspect of the pathogenesis of AIDS dementia. The study of host gene expression in HIV-1 associated brain disease will facilitate establishing new paradigms and mechanisms for pathogenesis. HIV with only 9 genes is able to destroy its host with more than 30,000 genes. We used gene chip technology (Affymetrix) of brain tissue from AIDS ...
متن کاملNeurodegenerative Disease Parkinson’s Disease
Oral levodopa remains the most effective symptomatic drug for Parkinson’s disease (PD); however, its long-term use is limited by the emergence of motor fluctuations and involuntary movements, particularly in young-onset patients. A growing number of pre-clinical and clinical studies suggest that non-physiological pulsatile stimulation of striatal dopamine (DA) receptors induced by the use of sh...
