[Focal brain lesions and language dysfunction].

To be a neurologist, training in cognitive/behavioral neuroscience is essential. In this review article, the author tries to emphasize the localization relationship between focal brain lesions and language dysfunction, by discussing from split-brain syndromes, hemispheric asymmetry, to pure word dumbness, pure word deafness (verbal auditory agnosia), pure agraphia, and pure word blindness (pure...

Segmentation of Focal Brain Lesions

Focal brain lesions are a consequence of head trauma, cerebral infarcts or intracerebral hemorrhages. In clinical practice, magnetic resonance imaging (MRI) is commonly used to reveal them. The segmentation task consists of finding the lesion borders. This problem is non-trivial because the lesion may be connected to other intracranial compartments with similar intensities. A new method for the...

Language, Music, and Brain

Introduction: Over the last centuries, scientists have been trying to figure out how the brain is learning the language. By 1980, the study of brain-language relationships was based on the study of human brain damage. But since 1980, neuroscience methods have greatly improved. There is controversy about where music, composition, or the perception of language and music are in the brain, or wheth...

Spreading depolarizations cycle around and enlarge focal ischaemic brain lesions

How does infarction in victims of stroke and other types of acute brain injury expand to its definitive size in subsequent days? Spontaneous depolarizations that repeatedly spread across the cerebral cortex, sometimes at remarkably regular intervals, occur in patients with all types of injury. Here, we show experimentally with in vivo real-time imaging that similar, spontaneous depolarizations ...
