The thalamus and basal ganglia: What is exactly where? A reply to 'Neuropsychological consequences of right thalamic injury: case study and review,' MJ Summers, Brain and Cognition 50 (2002).

Abstract The present paper re-analyzes anatomical and clinical data of a previous case report ( Summers, 2002 ). In this case study, a patient with severe neuropsychological and behavioral impairments is described and it is claimed that these impairments are causally linked to an right thalamic lesion. A simple method how to perform a lesion analysis is introduced which shows that PD’s lesion was a striatocapsular hematoma, and not a thalamic bleeding. The results of this anatomical re-analysis challenge the original behavioral-lesion hypothesis and emphasize the importance to provide appropriate data on brain lesions and clinical findings in neuropsychological case reports.
