Neural plasticity induced by stroke can mediate positive outcomes, such as recovery of function, but can also result in the formation of abnormal connections with negative consequences for perception and cognition. In three experiments using blood-oxygen level dependent (BOLD) functional magnetic resonance imaging, we examined the neural substrates of acquired auditory-tactile synesthesia, in which certain sounds can produce an intense somatosensory tingling sensation in a patient with a thalamic lesion. Compared with nine normal controls, the first experiment showed that the patient had a threefold greater BOLD response to sounds in the parietal operculum, the location of secondary somatosensory cortex. …

Aims: The etiology of stroke in young adults may be challenging. After preliminary investigations, a cause is not established in about one-third of patients. Cardiovascular embolism has been recognized as the cause of unexplained stroke or transient ischemic attack in a relevant number of young stroke patients. Materials and Methods: A 39-year-old right-handed woman was admitted to hospital with a left-side weakness of sudden onset. Her personal and family history were unremarkable except for several episodes of left arm weakness lasting for less than 10 minutes. On cranial magnetic resonance imaging, a right frontotemporal infarction was observed. Results: Laboratory work-up …
