Word Retrieval Learning Modulates Right Frontal Cortex in Patients with Left Frontal Damage
Previous studies have suggested that recovery or compensation of language function after a lesion in the left hemisphere may depend on mechanisms in the right hemisphere. However, a direct relationship between performance and right hemisphere activity has not been established. Here, we show that patients with left frontal lesions and partially recovered aphasia learn, at a normal rate, a novel ...
متن کاملDistinct patterns of word retrieval in right and left frontal lobe patients: a multidimensional perspective.
Several studies have shown that patients with frontal lobe damage (FL) generate fewer words than control participants in verbal fluency tasks. In the current study, we were interested in assessing the quality of such verbal fluency data. Multidimensional exploratory techniques, namely, hierarchical clustering (HC) and correspondence analysis (CoA), were performed on verbal fluency data collecte...
متن کاملLeft inferior frontal cortex and syntax: function, structure and behaviour in patients with left hemisphere damage
For the past 150 years, neurobiological models of language have debated the role of key brain regions in language function. One consistently debated set of issues concern the role of the left inferior frontal gyrus in syntactic processing. Here we combine measures of functional activity, grey matter integrity and performance in patients with left hemisphere damage and healthy participants to as...
متن کاملLeft frontal transcranial magnetic stimulation reduces contralesional extinction in patients with unilateral right brain damage.
It has been demonstrated previously that transcranial magnetic stimulation (TMS) of the sensorimotor cortex can induce transient suppression of the perception of cutaneous near-threshold stimuli from fingers of the contralateral hand in normal individuals. One explanation accounting for deficits in the exploration of contralateral space following a unilateral hemispheric lesion refers to a loss...
متن کاملWord Count : 8 , 085 Frontal Lobes and Memory Retrieval 1 Memory Retrieval and the Functional Organiza tion of Frontal Cortex
Controlling access to memory allows us to recover task-relevant information and to relate it to our decisions, actions, and goals. Neuropsychological and neuroimaging evidence suggests that memory control includes multiple component processes that depend on different regions of prefrontal cortex (PFC). Here, we highlight the distinction between PFC networks involved in controlling retrieval ver...
