Anton’s Syndrome following Callosal Disconnection
Anosognosia for cortical blindness, also called Anton's syndrome, is a rare neurological disorder usually following bilateral lesions to occipital cortices. Neuropsychological, morphological and functional neuroimaging (SPECT and fMRI) findings are reported in a patient who incurred Anton's syndrome after an ischaemic lesion confined to the left occipital lobe involving the corpus callosum. The...
متن کاملA Developmental Perspective in Learning the Mirror-Drawing Task
Is there late maturation of skill learning? This notion has been raised to explain an adult advantage in learning a variety of tasks, such as auditory temporal-interval discrimination, locomotion adaptation, and drawing visually-distorted spatial patterns (mirror-drawing, MD). Here, we test this assertion by following the practice of the MD task in two 5 min daily sessions separated by a 10 min...
متن کاملNeuropsychological studies of callosal agenesis
A developmental error or arrest during the foetal growth of the telencephalic midline can lead to partial or complete agenesis of the corpus callosum. A person who is born with no corpus callosum at all is likely also to lack the hippocampal commissure, but unlikely to lack the anterior commissure (Loeser & Alvord, 1968 a). Indeed, some congenitally acallosal individuals appear to have an enlar...

متن کاملConflict of intentions due to callosal disconnection.
OBJECTIVES Three patients with callosal syndrome manifested a peculiar symptom in that they were unable to perform intended whole body actions because another intention emerged in competition with the original one. Attempts were made to clarify the symptomatology of this manifestation and its possible mechanism is discussed. METHODS The three patients are described and previous reports on pat...
