Tools for the body (schema)
TLDR
Empirical support is presented for the notion that changes in specific neural networks that hold an updated map of body shape and posture are compatible with the inclusion of tools in the "Body Schema", as if the hand were elongated to the tip of the tool. Expand
Attentional load and sensory competition in human vision: modulation of fMRI responses by load at fixation during task-irrelevant stimulation in the peripheral visual field.
TLDR
The results reveal that task-dependent attentional load, and interhemifield stimulus-competition, can produce distinct influences on the neural responses to peripheral visual stimuli within the human visual system. Expand
Tool-use changes multimodal spatial interactions between vision and touch in normal humans
TLDR
It is shown that actively wielding tools can change this pattern of crossmodal interference, which depended on active tool-use, developing with increased experience in using the tool. Expand
Interhemispheric transmission of visuomotor information in humans: fMRI evidence.
TLDR
The aim of the experiment was to test the hypothesis that IT of visuomotor information requires the corpus callosum and to identify the cortical areas specifically activated during IT, and to discover whether IT occurs mainly at premotor or perceptual stages of information processing. Expand
Multisensory integration and the body schema: close to hand and within reach
TLDR
Converging evidence from animal and human studies suggests that the primate brain constructs various body-part-centred representations of space, based on the integration of visual, tactile and proprioceptive information. Expand
Somatic and Motor Components of Action Simulation
TLDR
By combining low-frequency repetitive and single-pulse transcranial magnetic stimulation, it is found that virtual lesions of ventral premotor cortex (vPMc) and primary somatosensory cortex (S1) suppressed mirror motor facilitation contingent upon observation of possible and impossible movements, respectively. Expand
Multisensory contributions to the 3-D representation of visuotactile peripersonal space in humans: evidence from the crossmodal congruency task
TLDR
The crossmodal congruency task has been used to investigate a number of questions related to the representation of space in both normal participants and brain-damaged patients, and areas of convergence with other cognitive neuroscience disciplines are highlighted. Expand
Active Tool Use with the Contralesional Hand Can Reduce Cross-modal Extinction of Touch on that Hand
TLDR
It is proposed that an actively used tool may be effective in linking cross-modal stimuli presented along its extension that can overcome competition between stimuli presented on opposite sides of the body midline, thus modulating extinction. Expand
The representation of space near the body through touch and vision
TLDR
It is concluded that visuo-tactile crossmodal links dominate the representation of near body space and that this is implemented functionally in parietal and premotor brain regions. Expand
Is the intact side really intact? Perseverative responses in patients with unilateral neglect: a productive manifestation
TLDR
Perseverative responses were found to be much more frequent in patients with spatial neglect and when the frontal lobe or subcortical structures were damaged, and in a group of patients suffering from senile dementia of the Alzheimer-type. Expand
