Abstract Analysis of error types provides useful information about the stages and processes
involved in normal and aphasic word production. In picture naming, semantic errors (horse …

It is thought that semantic memory represents taxonomic information differently from thematic
information. This study investigated the neural basis for the taxonomic-thematic distinction …

Studies of patients with acquired cognitive deficits following brain damage and studies using
contemporary neuroimaging techniques form two distinct streams of research on the neural …

Meaningful speech, as exemplified in object naming, calls on knowledge of the mappings
between word meanings and phonological forms. Phonological errors in naming (eg GHOST …

Neurologists and aphasiologists have debated for over a century whether right hemisphere
recruitment facilitates or impedes recovery from aphasia. Here we present a well-…

Lesion to symptom mapping (LSM) is a crucial tool for understanding the causality of brain-behavior
relationships. The analyses are typically performed by applying statistical methods …

Although evidence suggests that patients with left hemisphere strokes and non-fluent aphasia
who receive 1Hz repetitive transcranial magnetic stimulation (rTMS) over the intact right …

The dual-route interactive two-step model explains the variation in the error patterns of aphasic
speakers in picture naming, and word and nonword repetition tasks. The model has three …

Semantic errors in aphasia (eg, naming a horse as “dog”) frequently arise from faulty
mapping of concepts onto lexical items. A recent study by our group used voxel-based lesion-…

While evidence suggests that transcranial direct current stimulation (tDCS) may facilitate
language recovery in chronic post-stroke aphasia, individual variability in patient response to …
