Stereotaxic display of brain lesions.
Traditionally lesion location has been reported using standard templates, text based descriptions or representative raw slices from the patient's CT or MRI scan. Each of these methods has drawbacksExpand

Improving Lesion-Symptom Mapping
TLDR
Voxel-based lesion mapping can be used to determine relationships between behavioral measures and the location of brain injury, revealing the function of brain regions. Expand

The anatomy of spatial neglect based on voxelwise statistical analysis: a study of 140 patients.
A major challenge for any anatomical study of spatial neglect in neurological patients is that human lesions vary tremendously in extent and location between individuals. Approaches to this problemExpand

Non-spatially lateralized mechanisms in hemispatial neglect
Hemispatial neglect is a common, disabling disorder that results from brain damage, most frequently stroke. Research on patients with neglect has provided important insights into normal brainExpand

The anatomy of visual neglect.
The brain regions that are critically associated with visual neglect have become intensely disputed. In particular, one study of middle cerebral artery (MCA) stroke patients has claimed that the keyExpand

Using human brain lesions to infer function: a relic from a past era in the fMRI age?
Recent technological advances, such as functional imaging techniques, allow neuroscientists to measure and localize brain activity in healthy individuals. These techniques avoid many of theExpand

Using Transcranial Direct-Current Stimulation to Treat Stroke Patients With Aphasia
Background and Purpose— Recent research suggests that increased left hemisphere cortical activity, primarily of the left frontal cortex, is associated with improved naming performance in strokeExpand

Transcranial Direct Current Stimulation Improves Naming Reaction Time in Fluent Aphasia: A Double-Blind, Sham-Controlled Study
Background and Purpose— Previous evidence suggests that anodal transcranial direct current stimulation (A-tDCS) applied to the left hemisphere can improve aphasic participants' ability to name commonExpand

Spatial Normalization of Brain Images with Focal Lesions Using Cost Function Masking
TLDR
We use cost-function masking to reduce image mismatch between template and image at the site of the lesion. Expand
