In extinction neglect, what happens when stimuli is presented simultaneously from both sides?

When stimuli are presented simultaneously from both sides in the context of extinction neglect, patients typically demonstrate a tendency to respond primarily to the ipsilesional stimulus. This means that they focus on stimuli coming from the side of their body that is not affected by neglect, often disregarding or failing to perceive stimuli that originate from the contralesional side.

This phenomenon is significant in understanding the neural mechanisms of attention and awareness in stroke patients, particularly those with right hemisphere damage who may neglect stimuli on the left side. The result is a clear demonstration of attentional bias toward one side, which can be crucial in guiding rehabilitation strategies aimed at addressing these perceptual deficits in patients with neglect.
