It is possible to look at something while paying attention to something else. Vision and attention are not the same thing! The control of spatial attention is an essential cognitive function. While both hemispheres contribute to attentional control, the right hemisphere (rh) appears to have a much more substantial role to play. D(cid:455)sfu(cid:374)(cid:272)tio(cid:374) of the rh"s atte(cid:374)tional control network may result in subtle or profound impairments of attention. Both hemisphere control attention but right hemisphere is more important. If there is damage to right hemisphere there may be symptoms of impaired attention. Half of space is attentionally disturbed (not disturbed vision, disturbed attention: usually the left side of space caused by brain injury. Why the left side: attention (i. e. , conscious awareness) of the left side of space is systematically disrupted due to damage to the rh, which has more importance in controlling the attentional network.
