NEGLECT-LEFT OR RIGHT HEMISPHERE INVOLVEMENT

SUMMARY

1. Dominant (left) hemisphere is strongly oriented to the right hemi-space.

2. Non-dominant (right) hemisphere is equally oriented to both hemi-spaces.

3. Thus lesions of the left hemisphere do not lead to neglect, since the right is intact.

4. But lesions of the right hemisphere can lead to multi-modal neglect of the left hemi-space.
