DOI: 10.1002/ca.23373
Abstract: We aimed to clarify the clinical characteristics that affect visual perception (VP) and elucidate lesion locations correlated with impaired VP. We reviewed 61 patients with stroke. Clinical assessments of a motor‐free VP test were used… read more here.

DOI: 10.1002/hbm.26208
Abstract: Studies in patients with brain lesions play a fundamental role in unraveling the brain's functional anatomy. Lesion‐symptom mapping (LSM) techniques can relate lesion location to cognitive performance. However, a limitation of current LSM approaches is… read more here.

DOI: 10.1016/j.neuroimage.2017.08.036
Abstract: Abstract Past attempts to identify the neural substrates of hand and finger imitation skills in the left hemisphere of the brain have yielded inconsistent results. Here, we analyse those associations in a large sample of… read more here.

DOI: 10.1016/j.neuropsychologia.2019.107253
Abstract: Despite network studies of the human brain have brought consistent evidence of brain regions with diverse functional roles, the neuropsychological approach has mainly focused on the functional specialization of individual brain regions. Relatively few neuropsychological… read more here.

DOI: 10.1016/j.neuropsychologia.2021.108024
Abstract: Visuospatial neglect is a heterogenous syndrome which can occur following damage to either right or left hemisphere areas. This study employs voxel-lesion symptom mapping to identify the neural correlates of left and right egocentric and… read more here.

DOI: 10.1523/eneuro.0204-17.2017
Abstract: Abstract Lesion-symptom mapping is often employed to define brain structures that are crucial for human behavior. Even though poststroke deficits result from gray matter damage as well as secondary white matter loss, the impact of… read more here.

DOI: 10.3389/fneur.2020.00822
Abstract: Background: Diagnosing stroke as a cause of acute vertigo, dizziness, or double vision remains a challenge, because symptom characteristics can be variable. The purpose of this study was to prospectively investigate lesion-symptom relationships in patients… read more here.

DOI: 10.3389/fneur.2020.00854
Abstract: Background: Voxel-wise lesion-symptom mapping (VLSM) is a statistical technique to infer the structure-function relationship in patients with cerebral strokes. Previous VLSM research suggests that it is important to adjust for various confounders such as lesion… read more here.
