InExner first described a "graphic motor image center" in the middle frontal gyrus. Current psycholinguistic models of handwriting involve the conversion of abstract, orthographic representations into motor representations before a sequence of appropriate hand movements is produced.
Direct cortical stimulation and functional magnetic resonance imaging fMRI were used to study the human frontal areas involved in writing. Cortical electrical stimulation mapping was used intraoperatively in 12 patients during the removal of brain tumors to identify the areas involved in oral language sentence reading and naming and writing, and to spare them during surgery.
The fMRI activation experiment involved 12 right-handed and 12 left-handed healthy volunteers using word dictation without visual control and 2 control tasks. Direct cortical electrical stimulation of restricted areas rostral to the primary motor hand area Brodmann area [BA] 6 impaired handwriting in 6 patients, without disturbing hand movements or oral language tasks.
In 6 other patients, stimulation of lower frontal regions showed deficits combining handwriting with other language tasks.
DESCRIPTION: This is an extremely fine hand painted rendering of the Fuhrer intricately executed to the furthermost artistic degree of timberdesignmag.com painting depicts him in his brown political uniform. This was the official state service dress that he wore after his elevation to Reichs Chancellor in There is a growing body of evidence indicating a crucial role of Exner’s area in (hand-) writing symbolic codes such as letters and words. However, a recent study reported a patient with a lesion affecting Broca’s and Exner’s area, who suffered from severe peripheral .
