Visual presentation of single letters activates a premotor area involved in writing

Marieke Longcamp, Jean-Luc Anton, Muriel Roth, Jean-Luc Velay
2003 NeuroImage  
We established that the visual presentation of letters activated a part of the left premotor cortex (BA6) that was also activated when the letters were being written by the subjects.  ...  In the present fMRI study, we addressed the question as to whether motor-perceptual interactions might be involved in reading.  ...  Marieke Longcamp was supported by a fellowship from the French Research Ministry (A.C.I.

Letter processing automatically recruits a sensory–motor brain network

Karin H. James, Isabel Gauthier
2006 Neuropsychologia  
For the first time, we combine several letter processing tasks in a single experiment to study why letters seem to engage such disparate processing areas.  ...  Our results suggest involvement of these regions to different extents in different tasks.  ...  In one condin, subjects wrote letters based on the visual presentation of a ometrical shape ("write the first letter of the shape's name"), mpared to a control condition where they drew the shape elf.  ...

Left superior parietal cortex involvement in writing: integrating fMRI with lesion evidence

V Menon, J.E Desmond
2001 Cognitive Brain Research
